# xml_set_external_entity_ref_handler

(PHP 4, PHP 5)

xml_set_external_entity_ref_handler — Set up external entity reference handler

### Beschreibung

bool xml_set_external_entity_ref_handler ( resource `$parser` , callable `$handler` )

Sets the external entity reference handler function for the XML parser `parser`.

### Parameter-Liste

`parser`

  A reference to the XML parser to set up external entity reference handler function.

`handler`

  `handler` is a string containing the name of a function that must exist when xml_parse() is called for `parser`.

  The function named by `handler` must accept five parameters, and should return an integer value.If the value returned from the handler is `FALSE` (which it will be if no value is returned), the XML parser will stop parsing and xml_get_error_code() will return `XML_ERROR_EXTERNAL_ENTITY_HANDLING`.

  handler ( resource `$parser` , string `$open_entity_names` , string `$base` , string `$system_id` , string `$public_id` )
  `parser`
    The first parameter, parser, is a reference to the XML parser calling the handler.
  `open_entity_names`
    The second parameter, `open_entity_names`, is a space-separated list of the names of the entities that are open for the parse of this entity (including the name of the referenced entity).
  `base`
    This is the base for resolving the system identifier (`system_id`) of the external entity.Currently this parameter will always be set to an empty string.
  `system_id`
    The fourth parameter, `system_id`, is the system identifier as specified in the entity declaration.
  `public_id`
    The fifth parameter, `public_id`, is the public identifier as specified in the entity declaration, or an empty string if none was specified; the whitespace in the public identifier will have been normalized as required by the XML spec.

  If a handler function is set to an empty string, or `FALSE`, the handler in question is disabled.

  > Hinweis: Anstelle eines Funktionsnamens kann auch ein Array mit einer Objekt-Referenz und dem Namen einer Methode angegeben werden.
