# MongoCollection::batchInsert

(PECL mongo >=0.9.0)

MongoCollection::batchInsert — Inserts multiple documents into this collection

### Beschreibung

public mixed MongoCollection::batchInsert ( array `$a` [, array `$options` = array() ] )

### Parameter-Liste

`a`

  An array of arrays or objects. If any objects are used, they may not have protected or private properties.

  > Hinweis:

  > If the documents to insert do not have an _id key or property, a new MongoId instance will be created and assigned to it. See MongoCollection::insert() for additional information on this behavior.

`options`

  Options for the inserts.

  - "continueOnError"

    Boolean, defaults to `FALSE`. If set, the database will not stop processing a bulk insert if one fails (eg due to duplicate IDs). This makes bulk insert behave similarly to a series of single inserts, except that calling MongoDB::lastError() will have an error set if any insert fails, not just the last one. If multiple errors occur, only the most recent will be reported by MongoDB::lastError().

    > Hinweis:

    > Please note that continueOnError affects errors on the database side only. If you try to insert a document that has errors (for example it contains a key with an empty name), then the document is not even transferred to the database as the driver detects this error and bails out. continueOnError has no effect on errors detected in the documents by the driver.

  - "fsync"

    Boolean, defaults to `FALSE`. Forces the insert to be synced to disk before returning success. If `TRUE`, an acknowledged insert is implied and will override setting w to 0.

  - "j"

    Boolean, defaults to `FALSE`. Forces the insert to be synced to the journal before returning success. If `TRUE`, an acknowledged insert is implied and will override setting w to 0.

  - "w"

    See WriteConcerns. The default value for MongoClient is 1.

  - "wtimeout"

    How long to wait for WriteConcern acknowledgement. The default value for MongoClient is 10000 milliseconds.

  - "safe"

    Deprecated. Please use the WriteConcern w option.

  - "timeout"

    Integer, defaults to MongoCursor::$timeout. If acknowledged writes are used, this sets how long (in milliseconds) for the client to wait for a database response. If the database does not respond within the timeout period, a MongoCursorTimeoutException will be thrown.

### Rückgabewerte

If the w parameter is set to acknowledge the write, returns an associative array with the status of the inserts ("ok") and any error that may have occurred ("err"). Otherwise, returns `TRUE` if the batch insert was successfully sent, `FALSE` otherwise.

### Fehler/Exceptions

Throws MongoException if any inserted documents are empty or if they contains zero-length keys. Attempting to insert an object with protected and private properties will cause a zero-length key error.

Throws MongoCursorException if the "w" option is set and the write fails.

Throws MongoCursorTimeoutException if the "w" option is set to a value greater than one and the operation takes longer than MongoCursor::$timeout milliseconds to complete. This does not kill the operation on the server, it is a client-side timeout. The operation in MongoCollection::$wtimeout is milliseconds.

### Changelog

Version | Beschreibung
--- | ---
1.2.7 | Added "continueOnError" option.
1.0.9 | Added ability to pass integers to the "safe" option, which previously only accepted booleans. Added "fsync" option.
1.0.5 | Added `options` parameter.

### Beispiele

Beispiel #1 MongoCollection::batchInsert() example

Batch insertion is a quick way to add many elements to the database at once

`<?php
$users = array();
for ($i = 0; $i<100; $i++) {
$users[] = array('username' => 'user'.$i, 'i' => $i);
}
$mongo = new MongoClient();
$collection = $mongo->my_db->users;
$collection->drop();
$collection->batchInsert($users);
foreach ($users as $user) {
echo $user['_id']."\n"; // populated with instanceof MongoId
}
$users = $collection->find()->sort(array('i' => 1));
foreach ($users as $user) {
var_dump($user['username']);
}
?>`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    4bf43ac68ead0e1971000000
    4bf43ac68ead0e1971010000
    4bf43ac68ead0e1971020000
    ...
    string(5) "user1"
    string(5) "user2"
    string(5) "user3"
    ...

Beispiel #2 MongoCollection::batchInsert() example with ignoring errors

`<?php
$con = new Mongo;
$db = $con->demo;
$doc1 = array(
'_id' => new MongoId('4cb4ab6d7addf98506010001'),
'id' => 1,
'desc' => "ONE",
);
$doc2 = array(
'_id' => new MongoId('4cb4ab6d7addf98506010002'),
'id' => 2,
'desc' => "TWO",
);
$doc3 = array(
'_id' => new MongoId('4cb4ab6d7addf98506010002'), // same _id as above
'id' => 3,
'desc' => "THREE",
);
$doc4 = array(
'_id' => new MongoId('4cb4ab6d7addf98506010004'),
'id' => 4,
'desc' => "FOUR",
);
$c = $db->selectCollection('c');
$c->batchInsert(
array($doc1, $doc2, $doc3, $doc4),
array('continueOnError' => true)
);
$docs = $c->find();
foreach ($docs as $doc) {
var_dump($doc['desc']);
}
?>`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    string(3) "ONE"
    string(3) "TWO"
    string(4) "FOUR"
