# xml_set_start_namespace_decl_handler

(PHP 4 >= 4.0.5, PHP 5)

xml_set_start_namespace_decl_handler — Set up start namespace declaration handler

### Opis

bool xml_set_start_namespace_decl_handler ( resource `$parser` , callback `$handler` )

Set a handler to be called when a namespace is declared. Namespace declarations occur inside start tags. But the namespace declaration start handler is called before the start tag handler for each namespace declared in that start tag.

### Parametry

`parser`

  A reference to the XML parser.

`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 four 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 `$parser` , string `$user_data` , string `$prefix` , string `$uri` )
  `parser`
    The first parameter, parser, is a reference to the XML parser calling the handler.
  `user_data`
  `prefix`
  `uri`

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