xml_set_start_namespace_decl_handler

Parameters

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.

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