Configuration
=============

Almost all configurable data is placed in :file:`config.inc.php`. If this file
does not exist, please refer to the :ref:`setup` section to create one. This
file only needs to contain the parameters you want to change from their
corresponding default value in :file:`libraries/config.default.php`.

The parameters which relate to design (like colors) are placed in
:file:`themes/themename/layout.inc.php`. You might also want to create
:file:`config.footer.inc.php` and :file:`config.header.inc.php` files to add
your site specific code to be included on start and end of each page.

.. note::

    Some distributions (eg. Debian or Ubuntu) store :file:`config.inc.php` in
    ``/etc/phpmyadmin`` instead of within phpMyAdmin sources.

.. warning::

    :term:`Mac` users should note that if you are on a version before
    :term:`Mac OS X`, PHP does not seem to
    like :term:`Mac` end of lines character (``\r``). So
    ensure you choose the option that allows to use the \*nix end of line
    character (``\n``) in your text editor before saving a script you have
    modified.

Basic settings
--------------

.. config:option:: $cfg['PmaAbsoluteUri']

    :type: string
    :default: ``''``

    Sets here the complete :term:`URL` (with full path) to your phpMyAdmin
    installation's directory. E.g.
    ``http://www.example.net/path_to_your_phpMyAdmin_directory/``.  Note also
    that the :term:`URL` on some web servers are case–sensitive. Don’t forget
    the trailing slash at the end.

    Starting with version 2.3.0, it is advisable to try leaving this blank. In
    most cases phpMyAdmin automatically detects the proper setting. Users of
    port forwarding will need to set :config:option:`$cfg['PmaAbsoluteUri']`
    (`more info <https://sourceforge.net/p/phpmyadmin/support-requests/795/>`_).

    A good test is to browse a table, edit a row and save it. There should be
    an error message if phpMyAdmin is having trouble auto–detecting the correct
    value. If you get an error that this must be set or if the autodetect code
    fails to detect your path, please post a bug report on our bug tracker so
    we can improve the code.

    .. seealso:: :ref:`faq1_40`

.. config:option:: $cfg['PmaNoRelation_DisableWarning']

    :type: boolean
    :default: false

    Starting with version 2.3.0 phpMyAdmin offers a lot of features to
    work with master / foreign – tables (see :config:option:`$cfg['Servers'][$i]['pmadb']`).  
    
    If you tried to set this
    up and it does not work for you, have a look on the :guilabel:`Structure` page
    of one database where you would like to use it. You will find a link
    that will analyze why those features have been disabled.
    
    If you do not want to use those features set this variable to ``true`` to
    stop this message from appearing.

.. config:option:: $cfg['SuhosinDisableWarning']

    :type: boolean
    :default: false

    A warning is displayed on the main page if Suhosin is detected. 
    
    You can set this parameter to ``true`` to stop this message from appearing.

.. config:option:: $cfg['McryptDisableWarning']

    :type: boolean
    :default: false

    Disable the default warning that is displayed if mcrypt is missing for
    cookie authentication. 
    
    You can set this parameter to ``true`` to stop this message from appearing.

.. config:option:: $cfg['ServerLibraryDifference_DisableWarning']

    :type: boolean
    :default: false

    A warning is displayed on the main page if there is a difference
    between the MySQL library and server version. 
    
    You can set this parameter to ``true`` to stop this message from appearing.

.. config:option:: $cfg['ReservedWordDisableWarning']

    :type: boolean
    :default: false

    This warning is displayed on the Structure page of a table if one or more
    column names match with words which are MySQL reserved.

    If you want to turn off this warning, you can set it to ``true`` and 
    warning will not longer be displayed 

.. config:option:: $cfg['TranslationWarningThreshold']

    :type: integer
    :default: 80

    Show warning about incomplete translations on certain threshold.

Server connection settings
--------------------------

.. config:option:: $cfg['Servers']

    :type: array
    :default: one server array with settings listed bellow

    Since version 1.4.2, phpMyAdmin supports the administration of multiple
    MySQL servers. Therefore, a :config:option:`$cfg['Servers']`-array has been
    added which contains the login information for the different servers. The
    first :config:option:`$cfg['Servers'][$i]['host']` contains the hostname of
    the first server, the second :config:option:`$cfg['Servers'][$i]['host']`
    the hostname of the second server, etc. In
    :file:`libraries/config.default.php`, there is only one section for server
    definition, however you can put as many as you need in
    :file:`config.inc.php`, copy that block or needed parts (you don't have to
    define all settings, just those you need to change).

    .. note::
       
        The :config:option:`$cfg['Servers']` array starts with
        $cfg['Servers'][1]. Do not use $cfg['Servers'][0]. If you want more
        than one server, just copy following section (including $i
        incrementation) serveral times. There is no need to define full server
        array, just define values you need to change.


.. config:option:: $cfg['Servers'][$i]['host']

    :type: string
    :default: ``'localhost'``

    The hostname or :term:`IP` address of your $i-th MySQL-server. E.g.
    ``localhost``.

    Possible values are:

    * hostname, e.g., ``'localhost'`` or ``'mydb.example.org'``
    * IP address, e.g., ``'127.0.0.1'`` or ``'192.168.10.1'``
    * dot - ``'.'``, i.e., use named pipes on windows systems
    * empty - ``''``, disables this server

.. config:option:: $cfg['Servers'][$i]['port']

    :type: string
    :default: ``''``

    The port-number of your $i-th MySQL-server. Default is 3306 (leave
    blank). 
    
    .. note::
       
       If you use ``localhost`` as the hostname, MySQL ignores this port number
       and connects with the socket, so if you want to connect to a port
       different from the default port, use ``127.0.0.1`` or the real hostname
       in :config:option:`$cfg['Servers'][$i]['host']`.

.. config:option:: $cfg['Servers'][$i]['socket']

    :type: string
    :default: ``''``

    The path to the socket to use. Leave blank for default. To determine
    the correct socket, check your MySQL configuration or, using the
    :command:`mysql` command–line client, issue the ``status`` command. Among the
    resulting information displayed will be the socket used.

.. config:option:: $cfg['Servers'][$i]['ssl']

    :type: boolean
    :default: false

    Whether to enable SSL for connection to MySQL server.

.. config:option:: $cfg['Servers'][$i]['connect_type']

    :type: string
    :default: ``'tcp'``

    What type connection to use with the MySQL server. Your options are
    ``'socket'`` and ``'tcp'``. It defaults to tcp as that is nearly guaranteed
    to be available on all MySQL servers, while sockets are not supported on
    some platforms. To use the socket mode, your MySQL server must be on the
    same machine as the Web server.

.. config:option:: $cfg['Servers'][$i]['extension']

    :type: string
    :default: ``'mysqli'``

    What php MySQL extension to use for the connection. Valid options are:

    ``mysql``
        The classic MySQL extension. 

    ``mysqli`` 
        The improved MySQL extension. This extension became available with PHP
        5.0.0 and is the recommended way to connect to a server running MySQL
        4.1.x or newer.

.. config:option:: $cfg['Servers'][$i]['compress']

    :type: boolean
    :default: false

    Whether to use a compressed protocol for the MySQL server connection
    or not (experimental).

.. _controlhost:
.. config:option:: $cfg['Servers'][$i]['controlhost']

    :type: string
    :default: ``''``

    Permits to use an alternate host to hold the configuration storage
    data.

.. _controluser:
.. config:option:: $cfg['Servers'][$i]['controluser']

    :type: string
    :default: ``''``

.. config:option:: $cfg['Servers'][$i]['controlpass']

    :type: string
    :default: ``''``

    This special account is used for 2 distinct purposes: to make possible all
    relational features (see :config:option:`$cfg['Servers'][$i]['pmadb']`) and,
    for a MySQL server running with ``--skip-show-database``, to enable a
    multi-user installation (:term:`HTTP` or cookie
    authentication mode). 

    When using :term:`HTTP` or
    cookie authentication modes (or 'config' authentication mode since phpMyAdmin
    2.2.1), you need to supply the details of a MySQL account that has ``SELECT``
    privilege on the *mysql.user (all columns except "Password")*, *mysql.db (all
    columns)* and *mysql.tables\_priv (all columns except "Grantor" and
    "Timestamp")* tables. This account is used to check what databases the user
    will see at login.

    .. versionchanged:: 2.2.5 
        those were called ``stduser`` and ``stdpass``

    .. seealso:: :ref:`setup`, :ref:`authentication_modes`

.. config:option:: $cfg['Servers'][$i]['auth_type']

    :type: string
    :default: ``'cookie'``

    Whether config or cookie or :term:`HTTP` or signon authentication should be
    used for this server.

    * 'config' authentication (``$auth_type = 'config'``) is the plain old
      way: username and password are stored in :file:`config.inc.php`.
    * 'cookie' authentication mode (``$auth_type = 'cookie'``) as
      introduced in 2.2.3 allows you to log in as any valid MySQL user with
      the help of cookies. Username and password are stored in cookies
      during the session and password is deleted when it ends. This can also
      allow you to log in in arbitrary server if :config:option:`$cfg['AllowArbitraryServer']` enabled.
    * 'http' authentication (was
      called 'advanced' in previous versions and can be written also as
      'http') (``$auth_type = 'http';'``) as introduced in 1.3.0 allows you to log in as any
      valid MySQL user via HTTP-Auth.
    * 'signon' authentication mode (``$auth_type = 'signon'``) as
      introduced in 2.10.0 allows you to log in from prepared PHP session
      data or using supplied PHP script. This is useful for implementing
      single signon from another application. Sample way how to seed session
      is in signon example: :file:`examples/signon.php`. There is also
      alternative example using OpenID - :file:`examples/openid.php` and example
      for scripts based solution - :file:`examples/signon-script.php`. You need
      to configure :config:option:`$cfg['Servers'][$i]['SignonSession']` or 
      :config:option:`$cfg['Servers'][$i]['SignonScript']` and 
      :config:option:`$cfg['Servers'][$i]['SignonURL']` to use this authentication 
      method.

    .. seealso:: :ref:`authentication_modes`

.. _servers_auth_http_realm:
.. config:option:: $cfg['Servers'][$i]['auth_http_realm']

    :type: string
    :default: ``''``

    When using auth\_type = ``http``, this field allows to define a custom
    :term:`HTTP` Basic Auth Realm which will be displayed to the user. If not
    explicitly specified in your configuration, a string combined of
    "phpMyAdmin " and either :config:option:`$cfg['Servers'][$i]['verbose']` or
    :config:option:`$cfg['Servers'][$i]['host']` will be used.

.. _servers_auth_swekey_config:
.. config:option:: $cfg['Servers'][$i]['auth_swekey_config']

    :type: string
    :default: ``''``

    The name of the file containing :ref:`swekey` ids and login names for hardware
    authentication. Leave empty to deactivate this feature.

.. _servers_user:
.. config:option:: $cfg['Servers'][$i]['user']

    :type: string
    :default: ``'root'``

.. config:option:: $cfg['Servers'][$i]['password']

    :type: string
    :default: ``''``

    When using :config:option:`$cfg['Servers'][$i]['auth_type']` set to
    'config', this is the user/password-pair which phpMyAdmin will use to
    connect to the MySQL server. This user/password pair is not needed when
    :term:`HTTP` or cookie authentication is used
    and should be empty.

.. _servers_nopassword:
.. config:option:: $cfg['Servers'][$i]['nopassword']

    :type: boolean
    :default: false

    Allow attempt to log in without password when a login with password
    fails. This can be used together with http authentication, when
    authentication is done some other way and phpMyAdmin gets user name
    from auth and uses empty password for connecting to MySQL. Password
    login is still tried first, but as fallback, no password method is
    tried.

.. _servers_only_db:
.. config:option:: $cfg['Servers'][$i]['only_db']

    :type: string or array
    :default: ``''``

    If set to a (an array of) database name(s), only this (these)
    database(s) will be shown to the user. Since phpMyAdmin 2.2.1,
    this/these database(s) name(s) may contain MySQL wildcards characters
    ("\_" and "%"): if you want to use literal instances of these
    characters, escape them (I.E. use ``'my\_db'`` and not ``'my_db'``).

    This setting is an efficient way to lower the server load since the
    latter does not need to send MySQL requests to build the available
    database list. But **it does not replace the privileges rules of the
    MySQL database server**. If set, it just means only these databases
    will be displayed but **not that all other databases can't be used.**

    An example of using more that one database:

    .. code-block:: php
        
        $cfg['Servers'][$i]['only_db'] = array('db1', 'db2');

    .. versionchanged:: 4.0.0 
        Previous versions permitted to specify the display order of 
        the database names via this directive. 

.. config:option:: $cfg['Servers'][$i]['hide_db']

    :type: string
    :default: ``''``

    Regular expression for hiding some databases from unprivileged users.
    This only hides them from listing, but a user is still able to access
    them (using, for example, the SQL query area). To limit access, use
    the MySQL privilege system.  For example, to hide all databases
    starting with the letter "a", use

    .. code-block:: php

        $cfg['Servers'][$i]['hide_db'] = '^a';

    and to hide both "db1" and "db2" use

    .. code-block:: php

        $cfg['Servers'][$i]['hide_db'] = '^(db1|db2)$';

    More information on regular expressions can be found in the `PCRE
    pattern syntax
    <http://php.net/manual/en/reference.pcre.pattern.syntax.php>`_ portion
    of the PHP reference manual.

.. config:option:: $cfg['Servers'][$i]['verbose']

    :type: string
    :default: ``''``

    Only useful when using phpMyAdmin with multiple server entries. If
    set, this string will be displayed instead of the hostname in the
    pull-down menu on the main page. This can be useful if you want to
    show only certain databases on your system, for example. For HTTP
    auth, all non-US-ASCII characters will be stripped.

.. config:option:: $cfg['Servers'][$i]['pmadb']

    :type: string
    :default: ``''``

    The name of the database containing the phpMyAdmin configuration
    storage.  

    See the :ref:`linked-tables`  section in this document to see the benefits of
    this feature, and for a quick way of creating this database and the needed
    tables.  

    If you are the only user of this phpMyAdmin installation, you can use your
    current database to store those special tables; in this case, just put your
    current database name in :config:option:`$cfg['Servers'][$i]['pmadb']`. For a
    multi-user installation, set this parameter to the name of your central
    database containing the phpMyAdmin configuration storage.

.. _bookmark:
.. config:option:: $cfg['Servers'][$i]['bookmarktable']

    :type: string
    :default: ``''``

    Since release 2.2.0 phpMyAdmin allows users to bookmark queries. This
    can be useful for queries you often run. To allow the usage of this
    functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * enter the table name in :config:option:`$cfg['Servers'][$i]['bookmarktable']`


.. _relation:
.. config:option:: $cfg['Servers'][$i]['relation']

    :type: string
    :default: ``''``

    Since release 2.2.4 you can describe, in a special 'relation' table,
    which column is a key in another table (a foreign key). phpMyAdmin
    currently uses this to

    * make clickable, when you browse the master table, the data values that
      point to the foreign table;
    * display in an optional tool-tip the "display column" when browsing the
      master table, if you move the mouse to a column containing a foreign
      key (use also the 'table\_info' table); (see :ref:`faqdisplay`)
    * in edit/insert mode, display a drop-down list of possible foreign keys
      (key value and "display column" are shown) (see :ref:`faq6_21`)
    * display links on the table properties page, to check referential
      integrity (display missing foreign keys) for each described key;
    * in query-by-example, create automatic joins (see :ref:`faq6_6`)
    * enable you to get a :term:`PDF` schema of
      your database (also uses the table\_coords table).

    The keys can be numeric or character. 

    To allow the usage of this functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the relation table name in :config:option:`$cfg['Servers'][$i]['relation']`
    * now as normal user open phpMyAdmin and for each one of your tables
      where you want to use this feature, click :guilabel:`Structure/Relation view/`
      and choose foreign columns.

    .. note:: 
       
        In the current version, ``master_db`` must be the same as ``foreign_db``.
        Those columns have been put in future development of the cross-db
        relations.

.. _table_info:
.. config:option:: $cfg['Servers'][$i]['table_info']

    :type: string
    :default: ``''``

    Since release 2.3.0 you can describe, in a special 'table\_info'
    table, which column is to be displayed as a tool-tip when moving the
    cursor over the corresponding key. This configuration variable will
    hold the name of this special table. To allow the usage of this
    functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the table name in :config:option:`$cfg['Servers'][$i]['table\_info']` (e.g.
      ``pma__table_info``)
    * then for each table where you want to use this feature, click
      "Structure/Relation view/Choose column to display" to choose the
      column.

    .. seealso:: :ref:`faqdisplay`

.. _table_coords:
.. config:option:: $cfg['Servers'][$i]['table_coords']

    :type: string
    :default: ``''``

.. config:option:: $cfg['Servers'][$i]['pdf_pages']

    :type: string
    :default: ``''``

    Since release 2.3.0 you can have phpMyAdmin create :term:`PDF` pages
    showing the relations between your tables. To do this it needs two tables
    "pdf\_pages" (storing information about the available :term:`PDF` pages)
    and "table\_coords" (storing coordinates where each table will be placed on
    a :term:`PDF` schema output).  You must be using the "relation" feature. 

    To allow the usage of this functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the correct table names in
      :config:option:`$cfg['Servers'][$i]['table\_coords']` and
      :config:option:`$cfg['Servers'][$i]['pdf\_pages']`

    .. seealso:: :ref:`faqpdf`.

.. _col_com:
.. config:option:: $cfg['Servers'][$i]['column_info']

    :type: string
    :default: ``''``

    This part requires a content update!  Since release 2.3.0 you can
    store comments to describe each column for each table. These will then
    be shown on the "printview". 

    Starting with release 2.5.0, comments are consequently used on the table
    property pages and table browse view, showing up as tool-tips above the
    column name (properties page) or embedded within the header of table in
    browse view. They can also be shown in a table dump. Please see the
    relevant configuration directives later on. 

    Also new in release 2.5.0 is a MIME- transformation system which is also
    based on the following table structure. See :ref:`transformations` for
    further information. To use the MIME- transformation system, your
    column\_info table has to have the three new columns 'mimetype',
    'transformation', 'transformation\_options'.


    To allow the usage of this functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the table name in :config:option:`$cfg['Servers'][$i]['column\_info']` (e.g.
      ``pma__column_info``)
    * to update your PRE-2.5.0 Column\_comments Table use this:  and
      remember that the Variable in :file:`config.inc.php` has been renamed from
      :config:option:`$cfg['Servers'][$i]['column\_comments']` to
      :config:option:`$cfg['Servers'][$i]['column\_info']`

      .. code-block:: mysql

           ALTER TABLE `pma__column_comments`
           ADD `mimetype` VARCHAR( 255 ) NOT NULL,
           ADD `transformation` VARCHAR( 255 ) NOT NULL,
           ADD `transformation_options` VARCHAR( 255 ) NOT NULL;

.. _history:
.. config:option:: $cfg['Servers'][$i]['history']

    :type: string
    :default: ``''``

    Since release 2.5.0 you can store your :term:`SQL` history, which means all
    queries you entered manually into the phpMyAdmin interface. If you don't
    want to use a table-based history, you can use the JavaScript-based
    history. 

    Using that, all your history items are deleted when closing the window.
    Using :config:option:`$cfg['QueryHistoryMax']` you can specify an amount of
    history items you want to have on hold. On every login, this list gets cut
    to the maximum amount.

    The query history is only available if JavaScript is enabled in
    your browser. 

    To allow the usage of this functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the table name in :config:option:`$cfg['Servers'][$i]['history']` (e.g.
      ``pma__history``)

.. _recent:
.. config:option:: $cfg['Servers'][$i]['recent']

    :type: string
    :default: ``''``

    Since release 3.5.0 you can show recently used tables in the
    navigation panel. It helps you to jump across table directly, without
    the need to select the database, and then select the table. Using
    :config:option:`$cfg['NumRecentTables']` you can configure the maximum number
    of recent tables shown. When you select a table from the list, it will jump to
    the page specified in :config:option:`$cfg['NavigationTreeDefaultTabTable']`.


    Without configuring the storage, you can still access the recently used tables,
    but it will disappear after you logout. 

    To allow the usage of this functionality persistently:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the table name in :config:option:`$cfg['Servers'][$i]['recent']` (e.g.
      ``pma__recent``)

.. _table_uiprefs:
.. config:option:: $cfg['Servers'][$i]['table_uiprefs']

    :type: string
    :default: ``''``

    Since release 3.5.0 phpMyAdmin can be configured to remember several
    things (sorted column :config:option:`$cfg['RememberSorting']`, column order,
    and column visibility from a database table) for browsing tables. Without
    configuring the storage, these features still can be used, but the values will
    disappear after you logout. 

    To allow the usage of these functionality persistently:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the table name in :config:option:`$cfg['Servers'][$i]['table\_uiprefs']` (e.g.
      ``pma__table_uiprefs``)


.. _tracking:
.. config:option:: $cfg['Servers'][$i]['tracking']

    :type: string
    :default: ``''``

    Since release 3.3.x a tracking mechanism is available. It helps you to
    track every :term:`SQL` command which is
    executed by phpMyAdmin. The mechanism supports logging of data
    manipulation and data definition statements. After enabling it you can
    create versions of tables.  

    The creation of a version has two effects:

    * phpMyAdmin saves a snapshot of the table, including structure and
      indexes.
    * phpMyAdmin logs all commands which change the structure and/or data of
      the table and links these commands with the version number.

    Of course you can view the tracked changes. On the :guilabel:`Tracking`
    page a complete report is available for every version. For the report you
    can use filters, for example you can get a list of statements within a date
    range. When you want to filter usernames you can enter \* for all names or
    you enter a list of names separated by ','. In addition you can export the
    (filtered) report to a file or to a temporary database.

    To allow the usage of this functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the table name in :config:option:`$cfg['Servers'][$i]['tracking']` (e.g.
      ``pma__tracking``)


.. _tracking2:
.. config:option:: $cfg['Servers'][$i]['tracking_version_auto_create']

    :type: boolean
    :default: false

    Whether the tracking mechanism creates versions for tables and views
    automatically.

    If this is set to true and you create a table or view with

    * CREATE TABLE ...
    * CREATE VIEW ...

    and no version exists for it, the mechanism will create a version for
    you automatically.

.. _tracking3:
.. config:option:: $cfg['Servers'][$i]['tracking_default_statements']

    :type: string
    :default: ``'CREATE TABLE,ALTER TABLE,DROP TABLE,RENAME TABLE,CREATE INDEX,DROP INDEX,INSERT,UPDATE,DELETE,TRUNCATE,REPLACE,CREATE VIEW,ALTER VIEW,DROP VIEW,CREATE DATABASE,ALTER DATABASE,DROP DATABASE'``

    Defines the list of statements the auto-creation uses for new
    versions. 

.. _tracking4:
.. config:option:: $cfg['Servers'][$i]['tracking_add_drop_view']

    :type: boolean
    :default: true

    Whether a DROP VIEW IF EXISTS statement will be added as first line to
    the log when creating a view.

.. _tracking5:
.. config:option:: $cfg['Servers'][$i]['tracking_add_drop_table']

    :type: boolean
    :default: true

    Whether a DROP TABLE IF EXISTS statement will be added as first line
    to the log when creating a table.

.. _tracking6:
.. config:option:: $cfg['Servers'][$i]['tracking_add_drop_database']

    :type: boolean
    :default: true

    Whether a DROP DATABASE IF EXISTS statement will be added as first
    line to the log when creating a database.

.. _userconfig:
.. config:option:: $cfg['Servers'][$i]['userconfig']

    :type: string
    :default: ``''``

    Since release 3.4.x phpMyAdmin allows users to set most preferences by
    themselves and store them in the database.

    If you don't allow for storing preferences in
    :config:option:`$cfg['Servers'][$i]['pmadb']`, users can still personalize
    phpMyAdmin, but settings will be saved in browser's local storage, or, it
    is is unavailable, until the end of session.  

    To allow the usage of this functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the table name in :config:option:`$cfg['Servers'][$i]['userconfig']`



.. _designer_coords:
.. config:option:: $cfg['Servers'][$i]['designer_coords']

    :type: string
    :default: ``''``

    Since release 2.10.0 a Designer interface is available; it permits to
    visually manage the relations.  

    To allow the usage of this functionality:

    * set up :config:option:`$cfg['Servers'][$i]['pmadb']` and the phpMyAdmin configuration storage
    * put the table name in :config:option:`$cfg['Servers'][$i]['designer\_coords']`
      (e.g. ``pma__designer_coords``)



.. config:option:: $cfg['Servers'][$i]['MaxTableUiprefs']

    :type: integer
    :default: 100

    Maximum number of rows saved in
    :config:option:`$cfg['Servers'][$i]['table_uiprefs']` table. 

    When tables are dropped or renamed,
    :config:option:`$cfg['Servers'][$i]['table_uiprefs']` may contain invalid data
    (referring to tables which no longer exist). We only keep this number of newest
    rows in :config:option:`$cfg['Servers'][$i]['table_uiprefs']` and automatically
    delete older rows.

.. config:option:: $cfg['Servers'][$i]['AllowRoot']

    :type: boolean
    :default: true

    Whether to allow root access. This is just a shortcut for the
    :config:option:`$cfg['Servers'][$i]['AllowDeny']['rules']` below.

.. config:option:: $cfg['Servers'][$i]['AllowNoPassword']

    :type: boolean
    :default: false

    Whether to allow logins without a password. The default value of
    ``false`` for this parameter prevents unintended access to a MySQL
    server with was left with an empty password for root or on which an
    anonymous (blank) user is defined.

.. _servers_allowdeny_order:
.. config:option:: $cfg['Servers'][$i]['AllowDeny']['order']

    :type: string
    :default: ``''``

    If your rule order is empty, then :term:`IP`
    authorization is disabled. 

    If your rule order is set to
    ``'deny,allow'`` then the system applies all deny rules followed by
    allow rules. Access is allowed by default. Any client which does not
    match a Deny command or does match an Allow command will be allowed
    access to the server. 

    If your rule order is set to ``'allow,deny'``
    then the system applies all allow rules followed by deny rules. Access
    is denied by default. Any client which does not match an Allow
    directive or does match a Deny directive will be denied access to the
    server. 

    If your rule order is set to ``'explicit'``, authorization is
    performed in a similar fashion to rule order 'deny,allow', with the
    added restriction that your host/username combination **must** be
    listed in the *allow* rules, and not listed in the *deny* rules. This
    is the **most** secure means of using Allow/Deny rules, and was
    available in Apache by specifying allow and deny rules without setting
    any order. 

    Please also see :config:option:`$cfg['TrustedProxies']` for
    detecting IP address behind proxies.

.. _servers_allowdeny_rules:
.. config:option:: $cfg['Servers'][$i]['AllowDeny']['rules']

    :type: array of strings
    :default: array()

    The general format for the rules is as such:

    .. code-block:: none
        
        <'allow' | 'deny'> <username> [from] <ipmask>

    If you wish to match all users, it is possible to use a ``'%'`` as a
    wildcard in the *username* field.

    There are a few shortcuts you can
    use in the *ipmask* field as well (please note that those containing
    SERVER\_ADDRESS might not be available on all webservers):

    .. code-block:: none

        
        'all' -> 0.0.0.0/0
        'localhost' -> 127.0.0.1/8
        'localnetA' -> SERVER_ADDRESS/8
        'localnetB' -> SERVER_ADDRESS/16
        'localnetC' -> SERVER_ADDRESS/24

    Having an empty rule list is equivalent to either using ``'allow %
    from all'`` if your rule order is set to ``'deny,allow'`` or ``'deny %
    from all'`` if your rule order is set to ``'allow,deny'`` or
    ``'explicit'``.

    For the :term:`IP address` matching
    system, the following work: 

    * ``xxx.xxx.xxx.xxx`` (an exact :term:`IP address`) 
    * ``xxx.xxx.xxx.[yyy-zzz]`` (an :term:`IP address` range) 
    * ``xxx.xxx.xxx.xxx/nn`` (CIDR, Classless Inter-Domain Routing type :term:`IP` addresses) 

    But the following does not work: 

    * ``xxx.xxx.xxx.xx[yyy-zzz]`` (partial :term:`IP` address range) 

    For :term:`IPv6` addresses, the following work:

    * ``xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx`` (an exact :term:`IPv6` address)
    * ``xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:[yyyy-zzzz]`` (an :term:`IPv6` address range)
    * ``xxxx:xxxx:xxxx:xxxx/nn`` (CIDR, Classless Inter-Domain Routing type :term:`IPv6` addresses)

    But the following does not work:

    * ``xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xx[yyy-zzz]`` (partial :term:`IPv6` address range)

.. config:option:: $cfg['Servers'][$i]['DisableIS']

    :type: boolean
    :default: true

    Disable using ``INFORMATION_SCHEMA`` to retrieve information (use
    ``SHOW`` commands instead), because of speed issues when many
    databases are present. Currently used in some parts of the code, more
    to come.

.. config:option:: $cfg['Servers'][$i]['ShowDatabasesCommand']

    :type: string
    :default: ``'SHOW DATABASES'``

    On a server with a huge number of databases, the default ``SHOW DATABASES``
    command used to fetch the name of available databases will probably be too
    slow, so it can be replaced by faster commands. You can use ``#user#``
    string will be replaced by current user.

    When using ``false``, it will disable fetching databases from the server,
    only databases in :config:option:`$cfg['Servers'][$i]['only_db']` will be
    displayed.
    
    Examples:

    * ``'SHOW DATABASES'``
    * ``"SHOW DATABASES LIKE '#user#\_%'"``
    * ``'SELECT DISTINCT TABLE_SCHEMA FROM information_schema.SCHEMA_PRIVILEGES'``
    * ``'SELECT SCHEMA_NAME FROM information_schema.SCHEMATA'``
    * ``false``

.. config:option:: $cfg['Servers'][$i]['SignonScript']

    :type: string
    :default: ``''``

    Name of PHP script to be sourced and executed to obtain login
    credentials. This is alternative approach to session based single
    signon. The script needs to provide function
    ``get_login_credentials`` which returns list of username and
    password, accepting single parameter of existing username (can be
    empty). See :file:`examples/signon-script.php` for an example.

.. config:option:: $cfg['Servers'][$i]['SignonSession']

    :type: string
    :default: ``''``

    Name of session which will be used for signon authentication method.
    You should use something different than ``phpMyAdmin``, because this
    is session which phpMyAdmin uses internally. Takes effect only if 
    :config:option:`$cfg['Servers'][$i]['SignonScript']` is not configured.

.. config:option:: $cfg['Servers'][$i]['SignonURL']

    :type: string
    :default: ``''``

    :term:`URL` where user will be redirected
    to log in for signon authentication method. Should be absolute
    including protocol.

.. config:option:: $cfg['Servers'][$i]['LogoutURL']

    :type: string
    :default: ``''``

    :term:`URL` where user will be redirected
    after logout (doesn't affect config authentication method). Should be
    absolute including protocol.

.. config:option:: $cfg['Servers'][$i]['StatusCacheDatabases']

    :type: array of strings
    :default: array()

    Enables caching of ``TABLE STATUS`` outputs for specific databases on
    this server (in some cases ``TABLE STATUS`` can be very slow, so you
    may want to cache it). APC is used (if the PHP extension is available,
    if not, this setting is ignored silently). You have to provide 
    :config:option:`$cfg['Servers'][$i]['StatusCacheLifetime']`. 
    
    Takes effect only if :config:option:`$cfg['Servers'][$i]['DisableIS']` is
    ``true``.

.. config:option:: $cfg['Servers'][$i]['StatusCacheLifetime']

    :type: integer
    :default: 0

    Lifetime in seconds of the ``TABLE STATUS`` cache if 
    :config:option:`$cfg['Servers'][$i]['StatusCacheDatabases']` is used.

Generic settings
----------------

.. config:option:: $cfg['ServerDefault']

    :type: integer
    :default: 1

    If you have more than one server configured, you can set
    :config:option:`$cfg['ServerDefault']` to any one of them to autoconnect to that
    server when phpMyAdmin is started, or set it to 0 to be given a list
    of servers without logging in. 
    
    If you have only one server configured,
    :config:option:`$cfg['ServerDefault']` MUST be set to that server.

.. config:option:: $cfg['VersionCheck']

    :type: boolean
    :default: true

    Enables check for latest versions using javascript on main phpMyAdmin
    page.

    .. note::

        This setting can be adjusted by your vendor.

.. config:option:: $cfg['MaxDbList']

    :type: integer
    :default: 100

    The maximum number of database names to be displayed in the main panel's
    database list.

.. config:option:: $cfg['MaxNavigationItems']

    :type: integer
    :default: 25

    The number of items that can be displayed on each page of the
    navigation tree.

.. config:option:: $cfg['MaxTableList']

    :type: integer
    :default: 250

    The maximum number of table names to be displayed in the main panel's
    list (except on the Export page). This limit is also enforced in the
    navigation panel when in Light mode.

.. config:option:: $cfg['ShowHint']

    :type: boolean
    :default: true

    Whether or not to show hints (for example, hints when hovering over
    table headers).

.. config:option:: $cfg['MaxCharactersInDisplayedSQL']

    :type: integer
    :default: 1000

    The maximum number of characters when a :term:`SQL` query is displayed. The
    default limit of 1000 should be correct to avoid the display of tons of
    hexadecimal codes that represent BLOBs, but some users have real
    :term:`SQL` queries that are longer than 1000 characters. Also, if a
    query's length exceeds this limit, this query is not saved in the history.

.. config:option:: $cfg['PersistentConnections']

    :type: boolean
    :default: false

    Whether `persistent connections <http://php.net/manual/en/features
    .persistent-connections.php>`_ should be used or not. Works with
    following extensions:

    * mysql (`mysql\_pconnect <http://php.net/manual/en/function.mysql-
      pconnect.php>`_),
    * mysqli (requires PHP 5.3.0 or newer, `more information
      <http://php.net/manual/en/mysqli.persistconns.php>`_).

.. config:option:: $cfg['ForceSSL']

    :type: boolean
    :default: false

    Whether to force using https while accessing phpMyAdmin.

.. config:option:: $cfg['ExecTimeLimit']

    :type: integer [number of seconds]
    :default: 300

    Set the number of seconds a script is allowed to run. If seconds is
    set to zero, no time limit is imposed. This setting is used while
    importing/exporting dump files but has
    no effect when PHP is running in safe mode.

.. config:option:: $cfg['SessionSavePath']

    :type: string
    :default: ``''``

    Path for storing session data (`session\_save\_path PHP parameter
    <http://php.net/session_save_path>`_).

.. config:option:: $cfg['MemoryLimit']

    :type: string [number of bytes]
    :default: ``'0'``

    Set the number of bytes a script is allowed to allocate. If set to
    zero, no limit is imposed. 
    
    This setting is used while importing/exporting dump files and at some other
    places in phpMyAdmin so you definitely don't want to put here a too low
    value. It has no effect when PHP is running in safe mode. 
    
    You can also use any string as in :file:`php.ini`, eg. '16M'. Ensure you
    don't omit the suffix (16 means 16 bytes!)

.. config:option:: $cfg['SkipLockedTables']

    :type: boolean
    :default: false

    Mark used tables and make it possible to show databases with locked
    tables (since MySQL 3.23.30).

.. config:option:: $cfg['ShowSQL']

    :type: boolean
    :default: true

    Defines whether :term:`SQL` queries
    generated by phpMyAdmin should be displayed or not.

.. config:option:: $cfg['RetainQueryBox']

    :type: boolean
    :default: false

    Defines whether the :term:`SQL` query box
    should be kept displayed after its submission.

.. config:option:: $cfg['CodemirrorEnable']

    :type: boolean
    :default: true

    Defines whether to use a Javascript code editor for SQL query boxes.
    CodeMirror provides syntax highlighting and line numbers.  However,
    middle-clicking for pasting the clipboard contents in some Linux
    distributions (such as Ubuntu) is not supported by all browsers.

.. config:option:: $cfg['AllowUserDropDatabase']

    :type: boolean
    :default: false

    Defines whether normal users (non-administrator) are allowed to delete
    their own database or not. If set as false, the link :guilabel:`Drop
    Database` will not be shown, and even a ``DROP DATABASE mydatabase`` will
    be rejected. Quite practical for :term:`ISP` 's with many customers. 

    .. note:: 
       
        This limitation of :term:`SQL` queries is not
        as strict as when using MySQL privileges. This is due to nature of
        :term:`SQL` queries which might be quite
        complicated.  So this choice should be viewed as help to avoid accidental
        dropping rather than strict privilege limitation.

.. config:option:: $cfg['Confirm']

    :type: boolean
    :default: true

    Whether a warning ("Are your really sure...") should be displayed when
    you're about to lose data.

.. config:option:: $cfg['UseDbSearch']

    :type: boolean
    :default: true

    Define whether the "search string inside database" is enabled or not.

.. config:option:: $cfg['IgnoreMultiSubmitErrors']

    :type: boolean
    :default: false

    Define whether phpMyAdmin will continue executing a multi-query
    statement if one of the queries fails. Default is to abort execution.

Cookie authentication options
-----------------------------

.. config:option:: $cfg['blowfish_secret']

    :type: string
    :default: ``''``

    The "cookie" auth\_type uses blowfish algorithm to encrypt the
    password. If you are using the "cookie" auth\_type, enter here a
    random passphrase of your choice. It will be used internally by the
    blowfish algorithm: you won’t be prompted for this passphrase. There
    is no maximum length for this secret. 

    .. versionchanged:: 3.1.0
        Since version 3.1.0 phpMyAdmin can generate this on the fly, but it
        makes a bit weaker security as this generated secret is stored in
        session and furthermore it makes impossible to recall user name from
        cookie.

.. config:option:: $cfg['LoginCookieRecall']

    :type: boolean
    :default: true

    Define whether the previous login should be recalled or not in cookie
    authentication mode. 
    
    This is automatically disabled if you do not have
    configured :config:option:`$cfg['blowfish_secret']`.

.. config:option:: $cfg['LoginCookieValidity']

    :type: integer [number of seconds]
    :default: 1440

    Define how long a login cookie is valid. Please note that php
    configuration option `session.gc\_maxlifetime
    <http://php.net/manual/en/session.configuration.php#ini.session.gc-
    maxlifetime>`_ might limit session validity and if the session is lost,
    the login cookie is also invalidated. So it is a good idea to set
    ``session.gc_maxlifetime`` at least to the same value of
    :config:option:`$cfg['LoginCookieValidity']`.

.. config:option:: $cfg['LoginCookieStore']

    :type: integer [number of seconds]
    :default: 0

    Define how long login cookie should be stored in browser. Default 0
    means that it will be kept for existing session. This is recommended
    for not trusted environments.

.. config:option:: $cfg['LoginCookieDeleteAll']

    :type: boolean
    :default: true

    If enabled (default), logout deletes cookies for all servers,
    otherwise only for current one. Setting this to false makes it easy to
    forget to log out from other server, when you are using more of them.

.. _AllowArbitraryServer:
.. config:option:: $cfg['AllowArbitraryServer']

    :type: boolean
    :default: false

    If enabled, allows you to log in to arbitrary servers using cookie
    authentication.

    .. note::
       
        Please use this carefully, as this may allow users access to MySQL servers
        behind the firewall where your :term:`HTTP`
        server is placed.

Navigation panel setup
----------------------

.. config:option:: $cfg['NavigationTreeEnableGrouping']

    :type: boolean
    :default: true

    Defines whether to group the databases based on a common prefix
    in their name :config:option:`$cfg['NavigationTreeDbSeparator']`.

.. config:option:: $cfg['NavigationTreeDbSeparator']

    :type: string or array
    :default: ``'_'``

    The string used to separate the parts of the database name when
    showing them in a tree. Alternatively you can specify more strings in
    an array and all of them will be used as a separator.

.. config:option:: $cfg['NavigationTreeTableSeparator']

    :type: string or array
    :default: ``'__'``

    Defines a string to be used to nest table spaces. This means if you have
    tables like ``first__second__third`` this will be shown as a three-level
    hierarchy like: first > second > third.  If set to false or empty, the
    feature is disabled. NOTE: You should not use this separator at the
    beginning or end of a table name or multiple times after another without
    any other characters in between.

.. config:option:: $cfg['NavigationTreeTableLevel']

    :type: integer
    :default: 1

    Defines how many sublevels should be displayed when splitting up
    tables by the above separator.

.. config:option:: $cfg['NumRecentTables']

    :type: integer
    :default: 10

    The maximum number of recently used tables shown in the navigation
    panel. Set this to 0 (zero) to disable the listing of recent tables.

.. config:option:: $cfg['ShowTooltip']

    :type: boolean
    :default: true

    Defines whether to display item comments as tooltips in navigation
    panel or not.

.. config:option:: $cfg['NavigationDisplayLogo']

    :type: boolean
    :default: true

    Defines whether or not to display the phpMyAdmin logo at the top of
    the navigation panel.

.. config:option:: $cfg['NavigationLogoLink']

    :type: string
    :default: ``'index.php'``

    Enter :term:`URL` where logo in the
    navigation panel will point to. For use especially with self made
    theme which changes this.

.. config:option:: $cfg['NavigationLogoLinkWindow']

    :type: string
    :default: ``'main'``

    Whether to open the linked page in the main window (``main``) or in a
    new one (``new``). Note: use ``new`` if you are linking to
    ``phpmyadmin.net``.

.. config:option:: $cfg['NavigationTreeDisplayItemFilterMinimum']

    :type: integer
    :default: 30

    Defines the minimum number of items (tables, views, routines and
    events) to display a JavaScript filter box above the list of items in
    the navigation tree. 
    
    To disable the filter completely some high number can be used (e.g. 9999)

.. config:option:: $cfg['NavigationTreeDisplayDbFilterMinimum']

    :type: integer
    :default: 30

    Defines the minimum number of databases to display a JavaScript filter
    box above the list of databases in the navigation tree.
    
    To disable the filter completely some high number can be used
    (e.g. 9999)

.. config:option:: $cfg['NavigationDisplayServers']

    :type: boolean
    :default: true 

    Defines whether or not to display a server choice at the top of the
    navigation panel.

.. config:option:: $cfg['DisplayServersList']

    :type: boolean
    :default: false

    Defines whether to display this server choice as links instead of in a
    drop-down.

.. config:option:: $cfg['NavigationTreeDefaultTabTable']

    :type: string
    :default: ``'tbl_structure.php'``

    Defines the tab displayed by default when clicking the small icon next
    to each table name in the navigation panel. Possible values:

    * ``tbl_structure.php``
    * ``tbl_sql.php``
    * ``tbl_select.php``
    * ``tbl_change.php``
    * ``sql.php``

Main panel
----------

.. config:option:: $cfg['ShowStats']

    :type: boolean
    :default: true

    Defines whether or not to display space usage and statistics about
    databases and tables. Note that statistics requires at least MySQL
    3.23.3 and that, at this date, MySQL doesn't return such information
    for Berkeley DB tables.

.. config:option:: $cfg['ShowServerInfo']

    :type: boolean
    :default: true

    Defines whether to display detailed server information on main page.
    You can additionally hide more information by using 
    :config:option:`$cfg['Servers'][$i]['verbose']`.

.. config:option:: $cfg['ShowPhpInfo']

    :type: boolean
    :default: false

.. config:option:: $cfg['ShowChgPassword']

    :type: boolean
    :default: true

.. config:option:: $cfg['ShowCreateDb']

    :type: boolean
    :default: true

    Defines whether to display the :guilabel:`PHP information` and
    :guilabel:`Change password` links and form for creating database or not at
    the starting main (right) frame. This setting does not check MySQL commands
    entered directly. 
    
    Please note that to block the usage of ``phpinfo()`` in scripts, you have to
    put this in your :file:`php.ini`:

    .. code-block:: ini

        disable_functions = phpinfo()

    Also note that enabling the :guilabel:`Change password` link has no effect
    with config authentication mode: because of the hard coded password value
    in the configuration file, end users can't be allowed to change their
    passwords.

.. config:option:: $cfg['ShowAll']

    :type: boolean
    :default: false

    Defines whether a user should be displayed a "Show all" button in
    browse mode or not in all cases. By default it is shown only on small
    tables (less than 5 × :config:option:`$cfg['MaxRows']` rows) to avoid
    performance issues while getting too many rows.

.. config:option:: $cfg['MaxRows']

    :type: integer

    :type: boolean or string
    :default: ``'blob'``

    Defines whether ``BLOB`` or ``BINARY`` columns are protected from
    editing when browsing a table's content. Valid values are:

    * ``false`` to allow editing of all columns;
    * ``'blob'`` to allow editing of all columns except ``BLOBS``;
    * ``'noblob'`` to disallow editing of all columns except ``BLOBS`` (the

    Defines the maximum number of concurrent entries for the Insert page.

.. config:option:: $cfg['ForeignKeyMaxLimit']

    :type: integer
    :default: 100

    If there are fewer items than this in the set of foreign keys, then a
    drop-down box of foreign keys is presented, in the style described by
    the :config:option:`$cfg['ForeignKeyDropdownOrder']` setting.

.. config:option:: $cfg['ForeignKeyDropdownOrder']

    :type: array
    :default: array('content-id', 'id-content')

    For the foreign key drop-down fields, there are several methods of
    display, offering both the key and value data. The contents of the
    array should be one or both of the following strings: ``content-id``,
    ``id-content``.

Export and import settings
--------------------------

.. config:option:: $cfg['ZipDump']

    :type: boolean
    :default: true

.. config:option:: $cfg['GZipDump']

    :type: boolean
    :default: true

.. config:option:: $cfg['BZipDump']

    :type: boolean
    :default: true

    Defines whether to allow the use of zip/GZip/BZip2 compression when
    creating a dump file

.. config:option:: $cfg['CompressOnFly']

    :type: boolean
    :default: true

    Defines whether to allow on the fly compression for GZip/BZip2
    compressed exports. This doesn't affect smaller dumps and allows users
    to create larger dumps that won't otherwise fit in memory due to php
    memory limit. Produced files contain more GZip/BZip2 headers, but all
    normal programs handle this correctly.

.. config:option:: $cfg['Export']

    :type: array
    :default: array(...)

    In this array are defined default parameters for export, names of
    items are similar to texts seen on export page, so you can easily
    identify what they mean.

.. config:option:: $cfg['Export']['method']

    :type: string
    :default: ``'quick'``

    Defines how the export form is displayed when it loads. Valid values
    are:

    * ``quick`` to display the minimum number of options to configure
    * ``custom`` to display every available option to configure
    * ``custom-no-form`` same as ``custom`` but does not display the option
      of using quick export



.. config:option:: $cfg['Import']

    :type: array
    :default: array(...)

    In this array are defined default parameters for import, names of
    items are similar to texts seen on import page, so you can easily
    identify what they mean.


Tabs display settings
---------------------

.. config:option:: $cfg['PropertiesIconic']

    :type: string
    :default: ``'both'``

    If set to ``true``, will display icons instead of text for db and table
    properties links (like :guilabel:`Browse`, :guilabel:`Select`,
    :guilabel:`Insert`, ...) and for the menu tabs. Can be set to ``'both'`` 
    if you want icons AND text. When set to ``false``, will only show text.

.. config:option:: $cfg['PropertiesNumColumns']

    :type: integer
    :default: 1

    How many columns will be utilized to display the tables on the database
    property view? When setting this to a value larger than 1, the type of the
    database will be omitted for more display space.

.. config:option:: $cfg['DefaultTabServer']

    :type: string
    :default: ``'index.php'``

    Defines the tab displayed by default on server view. Possible values:

    * ``main.php`` (recommended for multi-user setups)
    * ``server_databases.php``,
    * ``server_status.php``
    * ``server_variables.php``
    * ``server_privileges.php``

.. config:option:: $cfg['DefaultTabDatabase']

    :type: string
    :default: ``'db_structure.php'``

    Defines the tab displayed by default on database view. Possible
    values: 
    
    * ``db_structure.php``
    * ``db_sql.php`` 
    * ``db_search.php``.

.. config:option:: $cfg['DefaultTabTable']

    :type: string
    :default: ``'sql.php'``

    Defines the tab displayed by default on table view. Possible values:

    * ``tbl_structure.php``
    * ``tbl_sql.php``
    * ``tbl_select.php``
    * ``tbl_change.php`` 
    * ``sql.php``

Documentation
-------------

.. config:option:: $cfg['MySQLManualBase']

    :type: string
    :default: ``'http://dev.mysql.com/doc/refman'``

    If set to an :term:`URL` which points to
    the MySQL documentation (type depends on
    :config:option:`$cfg['MySQLManualType']`), appropriate help links are
    generated. 

    See `MySQL Documentation page <http://dev.mysql.com/doc/>`_ for more
    information about MySQL manuals and their types.

.. config:option:: $cfg['MySQLManualType']

    :type: string
    :default: ``'viewable'``

    Type of MySQL documentation:

    * viewable - "viewable online", current one used on MySQL website
    * searchable - "Searchable, with user comments"
    * chapters - "HTML, one page per chapter"
    * big - "HTML, all on one page"
    * none - do not show documentation links

Languages
---------

.. config:option:: $cfg['DefaultLang']

    :type: string
    :default: ``'en'``

    Defines the default language to use, if not browser-defined or user-
    defined. The corresponding language file needs to be in
    locale/*code*/LC\_MESSAGES/phpmyadmin.mo.

.. config:option:: $cfg['DefaultConnectionCollation']

    :type: string
    :default: ``'utf8_general_ci'``

    Defines the default connection collation to use, if not user-defined.
    See the `MySQL documentation <http://dev.mysql.com/doc/mysql/en
    /charset-charsets.html>`_ for list of possible values. This setting is
    ignored when connected to Drizzle server.

.. config:option:: $cfg['Lang']

    :type: string
    :default: not set

    Force language to use. The corresponding language file needs to be in
    locale/*code*/LC\_MESSAGES/phpmyadmin.mo.

.. config:option:: $cfg['FilterLanguages']

    :type: string
    :default: ``''``

    Limit list of available languages to those matching the given regular
    expression. For example if you want only Czech and English, you should
    set filter to ``'^(cs|en)'``.

.. config:option:: $cfg['RecodingEngine']

    :type: string
    :default: ``'auto'``

    You can select here which functions will be used for character set
    conversion. Possible values are:

    * auto - automatically use available one (first is tested iconv, then
      recode)
    * iconv - use iconv or libiconv functions
    * recode - use recode\_string function
    * none - disable encoding conversion

    Enabled charset conversion activates a pull-down menu in the Export
    and Import pages, to choose the character set when exporting a file.
    The default value in this menu comes from
    :config:option:`$cfg['Export']['charset']` and :config:option:`$cfg['Import']['charset']`.

.. config:option:: $cfg['IconvExtraParams']

    :type: string
    :default: ``'//TRANSLIT'``

    Specify some parameters for iconv used in charset conversion. See
    `iconv documentation <http://www.gnu.org/software/libiconv/documentati
    on/libiconv/iconv_open.3.html>`_ for details. By default
    ``//TRANSLIT`` is used, so that invalid characters will be
    transliterated.

.. config:option:: $cfg['AvailableCharsets']

    :type: array
    :default: array(..._

    Available character sets for MySQL conversion. You can add your own
    (any of supported by recode/iconv) or remove these which you don't
    use. Character sets will be shown in same order as here listed, so if
    you frequently use some of these move them to the top.

Web server settings
-------------------

.. config:option:: $cfg['OBGzip']

    :type: string/boolean
    :default: ``'auto'``

    Defines whether to use GZip output buffering for increased speed in
    :term:`HTTP` transfers. Set to
    true/false for enabling/disabling. When set to 'auto' (string),
    phpMyAdmin tries to enable output buffering and will automatically
    disable it if your browser has some problems with buffering. IE6 with
    a certain patch is known to cause data corruption when having enabled
    buffering.

.. config:option:: $cfg['TrustedProxies']

    :type: array
    :default: array()

    Lists proxies and HTTP headers which are trusted for 
    :config:option:`$cfg['Servers'][$i]['AllowDeny']['order']`. This list is by
    default empty, you need to fill in some trusted proxy servers if you
    want to use rules for IP addresses behind proxy. 

    The following example specifies that phpMyAdmin should trust a
    HTTP\_X\_FORWARDED\_FOR (``X -Forwarded-For``) header coming from the proxy
    1.2.3.4:

    .. code-block:: php
        
        $cfg['TrustedProxies'] = array('1.2.3.4' => 'HTTP_X_FORWARDED_FOR');

    The :config:option:`$cfg['Servers'][$i]['AllowDeny']['rules']` directive uses the
    client's IP address as usual.

.. config:option:: $cfg['GD2Available']

    :type: string
    :default: ``'auto'``

    Specifies whether GD >= 2 is available. If yes it can be used for MIME
    transformations. Possible values are:

    * auto - automatically detect
    * yes - GD 2 functions can be used
    * no - GD 2 function cannot be used

.. config:option:: $cfg['CheckConfigurationPermissions']

    :type: boolean
    :default: true

    We normally check the permissions on the configuration file to ensure
    it's not world writable. However, phpMyAdmin could be installed on a
    NTFS filesystem mounted on a non-Windows server, in which case the
    permissions seems wrong but in fact cannot be detected. In this case a
    sysadmin would set this parameter to ``false``.

.. config:option:: $cfg['LinkLengthLimit']

    :type: integer
    :default: 1000

    Limit for length of :term:`URL` in links.  When length would be above this
    limit, it is replaced by form with button. This is required as some web
    servers (:term:`IIS`) have problems with long :term:`URL` .
 
.. config:option:: $cfg['CSPAllow']

    :type: string
    :default: ``''``

    Additional string to include in allowed script sources in Content Security
    Policy header.

    This can be useful when you want to include some external javascript files
    in :file:`config.footer.inc.php` or :file:`config.header.inc.php`, which
    would be normally not allowed by Content Security Policy.

.. config:option:: $cfg['DisableMultiTableMaintenance']

    :type: boolean
    :default: false

    In the database Structure page, it's possible to mark some tables then
    choose an operation like optimizing for many tables. This can slow
    down a server; therefore, setting this to ``true`` prevents this kind
    of multiple maintenance operation.

Theme settings
--------------

.. config:option:: $cfg['NaviWidth']

    :type: integer
    :default:

    Navigation panel width in pixels. See

    :default:

.. config:option:: $cfg['BrowseMarkerColor']

    :type: string [CSS color]
    :default:

    The colors (HTML) uses for the pointer and the marker in browse mode.
    The former feature highlights the row over which your mouse is passing
    and the latter lets you visually mark/unmark rows by clicking on the
    corresponding checkbox. Highlighting / marking a column is done by
    hovering over / clicking the column's header (outside of the text).
    See :file:`themes/themename/layout.inc.php`.

.. config:option:: $cfg['FontFamily']

    :type: string
    :default:

    You put here a valid CSS font family value, for example ``arial, sans-
    serif``. See :file:`themes/themename/layout.inc.php`.

    :type: string
    :default:

    You put here a valid CSS font family value, for example ``monospace``.
    This one is used in textarea. See :file:`themes/themename/layout.inc.php`.

Design customization
--------------------

.. config:option:: $cfg['NavigationTreePointerEnable']

    :type: boolean
    :default: true

    A value of ``true`` activates the navi pointer.

.. config:option:: $cfg['BrowsePointerEnable']

    :type: boolean
    :default: true

    Whether to activate the browse pointer or not.

.. config:option:: $cfg['BrowseMarkerEnable']

    :type: boolean
    :default: true

    Whether to activate the browse marker or not.

.. config:option:: $cfg['LimitChars']

    :type: integer
    :default: 50

    Maximum number of characters shown in any non-numeric field on browse
    view. Can be turned off by a toggle button on the browse page.

.. config:option:: $cfg['RowActionLinks']

    :type: string
    :default: ``'left'``

    Defines the place where table row links (Edit, Copy, Delete) would be
    put when tables contents are displayed (you may have them displayed at
    the left side, right side, both sides or nowhere). "left" and "right"
    are parsed as "top" and "bottom" with vertical display mode.

.. config:option:: $cfg['DefaultDisplay']

    :type: string
    :default: ``'horizonta'``

    There are 3 display modes: horizontal, horizontalflipped and vertical.
    Define which one is displayed by default. The first mode displays each
    row on a horizontal line, the second rotates the headers by 90
    degrees, so you can use descriptive headers even though columns only
    contain small values and still print them out. The vertical mode sorts
    each row on a vertical lineup.

.. config:option:: $cfg['RememberSorting']

    :type: boolean
    :default: true

    If enabled, remember the sorting of each table when browsing them.

.. config:option:: $cfg['HeaderFlipType']

    :type: string
    :default: ``'auto'``

    The HeaderFlipType can be set to 'auto', 'css' or 'fake'. When using
    'css' the rotation of the header for horizontalflipped is done via
    CSS. The CSS transformation currently works only in Internet
    Explorer.If set to 'fake' PHP does the transformation for you, but of
    course this does not look as good as CSS. The 'auto' option enables
    CSS transformation when browser supports it and use PHP based one
    otherwise.

.. config:option:: $cfg['ShowBrowseComments']

    :type: boolean
    :default: true

.. config:option:: $cfg['ShowPropertyComments']

    :type: boolean
    :default: true

    By setting the corresponding variable to ``true`` you can enable the
    display of column comments in Browse or Property display. In browse
    mode, the comments are shown inside the header. In property mode,
    comments are displayed using a CSS-formatted dashed-line below the
    name of the column. The comment is shown as a tool-tip for that
    column.

Text fields
-----------

.. config:option:: $cfg['CharEditing']

    :type: string
    :default: ``'input'``

    Defines which type of editing controls should be used for CHAR and
    VARCHAR columns. Possible values are:

    * input - this allows to limit size of text to size of columns in MySQL,
      but has problems with newlines in columns
    * textarea - no problems with newlines in columns, but also no length
      limitations

.. config:option:: $cfg['MinSizeForInputField']

    :type: integer
    :default: 4

    Defines the minimum size for input fields generated for CHAR and
    VARCHAR columns.

    Number of columns and rows for the textareas. This value will be
    emphasized (\*2) for :term:`SQL` query
    textareas and (\*1.25) for :term:`SQL`
    textareas inside the query window.

    The Char\* values are used for CHAR
    and VARCHAR editing (if configured via :config:option:`$cfg['CharEditing']`).

.. config:option:: $cfg['LongtextDoubleTextarea']

    :type: boolean
    :default: true

    Defines whether textarea for LONGTEXT columns should have double size.

.. config:option:: $cfg['TextareaAutoSelect']

    :type: boolean

    :type: string
    :default: ``''``

    The name of the directory where :term:`SQL` files have been uploaded by
    other means than phpMyAdmin (for example, ftp). Those files are available
    under a drop-down box when you click the database or table name, then the
    Import tab. 

    If
    you want different directory for each user, %u will be replaced with
    username. 

    Please note that the file names must have the suffix ".sql"
    (or ".sql.bz2" or ".sql.gz" if support for compressed formats is
    enabled).

    This feature is useful when your file is too big to be
    uploaded via :term:`HTTP`, or when file
    uploads are disabled in PHP.

    .. note::
       
        If PHP is running in safe mode, this directory must be owned by the same
        user as the owner of the phpMyAdmin scripts.  See also :ref:`faq1_16` for
        alternatives.

    .. note:: 
       
        If PHP is running in safe mode, this directory must be owned by the same
        user as the owner of the phpMyAdmin scripts.

.. config:option:: $cfg['TempDir']

    :type: string
    :default: ``''``

    The name of the directory where temporary files can be stored. 

    This is needed for importing ESRI Shapefiles, see :ref:`faq6_30` and to
    work around limitations of ``open_basedir`` for uploaded files, see
    :ref:`faq1_11`.  

    If the directory where phpMyAdmin is installed is
    subject to an ``open_basedir`` restriction, you need to create a
    temporary directory in some directory accessible by the web server.
    However for security reasons, this directory should be outside the
    tree published by webserver. If you cannot avoid having this directory
    published by webserver, place at least an empty :file:`index.html` file
    there, so that directory listing is not possible.

    This directory should have as strict permissions as possible as the only
    user required to access this directory is the one who runs the webserver.
    If you have root privileges, simply make this user owner of this directory
    and make it accessible only by it:

    .. code-block:: sh

        
        chown www-data:www-data tmp
        chmod 700 tmp

    If you cannot change owner of the directory, you can achieve a similar
    setup using :term:`ACL`:

    .. code-block:: sh

        chmod 700 tmp
        setfacl -m "g:www-data:rwx" tmp
        setfacl -d -m "g:www-data:rwx" tmp

    If neither of above works for you, you can still make the directory
    :command:`chmod 777`, but it might impose risk of other users on system
    reading and writing data in this directory.

Various display setting
-----------------------

.. config:option:: $cfg['ShowDisplayDirection']

    :type: boolean
    :default: false

    Defines whether or not type display direction option is shown when
    browsing a table.

.. config:option:: $cfg['RepeatCells']

    :type: integer
    :default: 100

    Repeat the headers every X cells, or 0 to deactivate.

.. config:option:: $cfg['EditInWindow']

    :type: boolean
    :default: true

.. config:option:: $cfg['QueryWindowWidth']

    :type: integer
    :default: 550

.. config:option:: $cfg['QueryWindowHeight']

    :type: integer
    :default: 310

.. config:option:: $cfg['QueryHistoryDB']

    :type: boolean
    :default: false

.. config:option:: $cfg['QueryWindowDefTab']

    :type: string
    :default: ``'sql'``

.. config:option:: $cfg['QueryHistoryMax']

    :type: integer
    :default: 25

    All those variables affect the query window feature. A :term:`SQL` link or
    icon is always displayed in the navigation panel. If JavaScript is enabled
    in your browser, a click on this opens a distinct query window, which is a
    direct interface to enter :term:`SQL` queries. Otherwise, the right panel
    changes to display a query box. 

    The size of this query window can be customized with
    :config:option:`$cfg['QueryWindowWidth']` and
    :config:option:`$cfg['QueryWindowHeight']` - both integers for the size in
    pixels.  Note that normally, those parameters will be modified in
    :file:`layout.inc.php`` for the theme you are using. 

    If :config:option:`$cfg['EditInWindow']` is set to true, a click on [Edit]
    from the results page (in the :guilabel:`Showing Rows` section) opens the
    query window and puts the current query inside it. If set to false,
    clicking on the link puts the :term:`SQL` query
    in the right panel's query box.  

    If :config:option:`$cfg['QueryHistoryDB']` is set to ``true``, all your
    Queries are logged to a table, which has to be created by you (see
    :config:option:`$cfg['Servers'][$i]['history']`). If set to false, all your
    queries will be appended to the form, but only as long as your window is
    opened they remain saved.  

    When using the JavaScript based query window, it will always get updated
    when you click on a new table/db to browse and will focus if you click on
    :guilabel:`Edit SQL` after using a query. You can suppress updating the
    query window by checking the box :guilabel:`Do not overwrite this query
    from outside the window` below the query textarea. Then you can browse
    tables/databases in the background without losing the contents of the
    textarea, so this is especially useful when composing a query with tables
    you first have to look in. The checkbox will get automatically checked
    whenever you change the contents of the textarea. Please uncheck the button
    whenever you definitely want the query window to get updated even though
    you have made alterations. 

    If :config:option:`$cfg['QueryHistoryDB']` is set to ``true`` you can
    specify the amount of saved history items using
    :config:option:`$cfg['QueryHistoryMax']`. 

    The query window also has a custom tabbed look to group the features.
    Using the variable :config:option:`$cfg['QueryWindowDefTab']` you can
    specify the default tab to be used when opening the query window. It can be
    set to either ``sql``, ``files``, ``history`` or ``full``.

.. config:option:: $cfg['BrowseMIME']

    :type: boolean
    :default: true

    Enable :ref:`transformations`.

.. config:option:: $cfg['MaxExactCount']

    :type: integer
    :default: 0

    For InnoDB tables, determines for how large tables phpMyAdmin should
    get the exact row count using ``SELECT COUNT``. If the approximate row
    count as returned by ``SHOW TABLE STATUS`` is smaller than this value,
    ``SELECT COUNT`` will be used, otherwise the approximate count will be
    used.

.. config:option:: $cfg['MaxExactCountViews']

    :type: integer
    :default: 0

    For VIEWs, since obtaining the exact count could have an impact on
    performance, this value is the maximum to be displayed, using a
    ``SELECT COUNT ... LIMIT``. Setting this to 0 bypasses any row
    counting.

.. config:option:: $cfg['NaturalOrder']

    :type: boolean
    :default: true

    Sorts database and table names according to natural order (for
    example, t1, t2, t10). Currently implemented in the navigation panel
    and in Database view, for the table list.

.. config:option:: $cfg['InitialSlidersState']

    :type: string
    :default: ``'closed'``

    If set to ``'closed'``, the visual sliders are initially in a closed
    state. A value of ``'open'`` does the reverse. To completely disable
    all visual sliders, use ``'disabled'``.

.. config:option:: $cfg['UserprefsDisallow']

    :type: array
    :default: array()

    Contains names of configuration options (keys in ``$cfg`` array) that
    users can't set through user preferences. For possible values, refer
    to :file:`libraries/config/user_preferences.forms.php`.

.. config:option:: $cfg['UserprefsDeveloperTab']

    :type: boolean
    :default: false

    Activates in the user preferences a tab containing options for
    developers of phpMyAdmin.

Page titles
-----------

.. config:option:: $cfg['TitleTable']

    :type: string
    :default: ``'@HTTP_HOST@ / @VSERVER@ / @DATABASE@ / @TABLE@ | @PHPMYADMIN@'``

.. config:option:: $cfg['TitleDatabase']

    :type: string
    :default: ``'@HTTP_HOST@ / @VSERVER@ / @DATABASE@ | @PHPMYADMIN@'``

.. config:option:: $cfg['TitleServer']

    :type: string
    :default: ``'@HTTP_HOST@ / @VSERVER@ | @PHPMYADMIN@'``

.. config:option:: $cfg['TitleDefault']

    :type: string
    :default: ``'@HTTP_HOST@ | @PHPMYADMIN@'``

    Allows you to specify window's title bar. You can use :ref:`faq6_27`.

Theme manager settings
----------------------

.. config:option:: $cfg['ThemePath']

    :type: string
    :default: ``'./themes'``

    If theme manager is active, use this as the path of the subdirectory
    containing all the themes.

.. config:option:: $cfg['ThemeManager']

    :type: boolean
    :default: true

    Enables user-selectable themes. See :ref:`faqthemes`.

.. config:option:: $cfg['ThemeDefault']

    :type: string
    :default: ``'pmahomme'``

    The default theme (a subdirectory under :config:option:`$cfg['ThemePath']`).

.. config:option:: $cfg['ThemePerServer']

    :type: boolean
    :default: false

    Whether to allow different theme for each server.

Default queries
---------------

.. config:option:: $cfg['DefaultQueryTable']

    :type: string
    :default: ``'SELECT * FROM @TABLE@ WHERE 1'``

.. config:option:: $cfg['DefaultQueryDatabase']

    :type: string
    :default: ``''``

    Default queries that will be displayed in query boxes when user didn't
    specify any. You can use standard :ref:`faq6_27`.

SQL parser settings
-------------------

.. config:option:: $cfg['SQP']['fmtType']

    :type: string
    :default: ``'html'``

    The main use of the new :term:`SQL` Parser
    is to pretty-print :term:`SQL` queries. By
    default we use HTML to format the query, but you can disable this by
    setting this variable to ``'none'``.

    Available options:

    * ``'html'``
    * ``'none'``

.. _cfg_SQP:
.. config:option:: $cfg['SQP']['fmtInd']

    :type: float
    :default: ``'1'``

.. config:option:: $cfg['SQP']['fmtIndUnit']

    :type: string
    :default: ``'em'``

    For the pretty-printing of :term:`SQL` queries,
    under some cases the part of a query inside a bracket is indented. By
    changing :config:option:`$cfg['SQP']['fmtInd']` you can change the amount
    of this indent. 

    Related in purpose is :config:option:`$cfg['SQP']['fmtIndUnit']` which
    specifies the units of the indent amount that you specified. This is used
    via stylesheets.

    You can use any HTML unit, for example:

    * ``'em'``
    * ``'ex'``
    * ``'pt'``
    * ``'px'``

.. config:option:: $cfg['SQP']['fmtColor']

    :type: array of string tuples
    :default:

    This array is used to define the colours for each type of element of
    the pretty-printed :term:`SQL` queries.
    The tuple format is *class* => [*HTML colour code* | *empty string*]


    If you specify an empty string for the color of a class, it is ignored
    in creating the stylesheet. You should not alter the class names, only
    the colour strings.

SQL validator settings
----------------------

.. config:option:: $cfg['SQLValidator']

    :type: array
    :default: array(...)



.. config:option:: $cfg['SQLValidator']['use']

    :type: boolean
    :default: false

    phpMyAdmin now supports use of the `Mimer SQL Validator
    <http://developer.mimer.com/validator/index.htm>`_ service, as originally
    published on `Slashdot
    <http://developers.slashdot.org/article.pl?sid=02/02/19/1720246>`_. For
    help in setting up your system to use the service, see the
    :ref:`faqsqlvalidator`.

.. config:option:: $cfg['SQLValidator']['username']

    :type: string
    :default: ``''``

.. config:option:: $cfg['SQLValidator']['password']

    :type: string
    :default: ``''``

    The SOAP service allows you to log in with ``anonymous`` and any password,
    so we use those by default. Instead, if you have an account with them, you
    can put your login details here, and it will be used in place of the
    anonymous login.

--------------

.. config:option:: $cfg['DefaultFunctions']

    :type: array
    :default: array(...)

    Functions selected by default when inserting/changing row, Functions
    are defined for meta types as (FUNC\_NUMBER, FUNC\_DATE, FUNC\_CHAR,
    FUNC\_SPATIAL, FUNC\_UUID) and for ``first_timestamp``, which is used
    for first timestamp column in table.
