xml_set_external_entity_ref_handler - Set up external entity reference handler

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

DESCRIPTION
	Sets the external entity reference handler function for the XML parser $parser.

PARAMETERS
	      o $parser
		- A reference to the XML parser to set up external entity reference handler function.

	      o $handler
		-$handler  is  a  string  containing the name of a function that must exist when xml_parse(3) 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(3) will return
		XML_ERROR_EXTERNAL_ENTITY_HANDLING.
		 handler (resource  $parser, string  $open_entity_names, string  $base, string	$system_id, string  $public_id)

		     o $parser
		       - The first parameter, parser, is a reference to the XML parser calling the handler.

		     o $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).

		     o $base
		       -  This	is  the base for resolving the system identifier ($system_id) of the external entity.Currently this parameter will
		       always be set to an empty string.

		     o $system_id
		       - The fourth parameter, $system_id, is the system identifier as specified in the entity declaration.

		     o $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.

	      Note

		     Instead of a function name, an array containing an object reference and a method name can also be supplied.

RETURN VALUES
	Returns TRUE on success or FALSE on failure.
