xml_set_end_namespace_decl_handler

(PHP 4 >= 4.0.5, PHP 5, PHP 7, PHP 8)

xml_set_end_namespace_decl_handler — Set up end namespace declaration handler

Description

xml_set_end_namespace_decl_handler(XMLParser $parser, callable $handler): true

Set a handler to be called when leaving the scope of a namespace declaration. This will be called, for each namespace declaration, after the handler for the end tag of the element in which the namespace was declared.

Caution

This event is not supported under libXML, so a registered handler wouldn't be called.

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 two 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(XMLParser $parser, string $prefix)

parser: The first parameter, parser, is a reference to the XML parser calling the handler.
prefix: The prefix is a string used to reference the namespace within an XML object.

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

Always returns true.

Changelog

Version	Description
8.0.0	`parser` expects an XMLParser instance now; previously, a valid `xml` resource was expected.
