xml_set_character_data_handlerSet up character data handler

Description

xml_set_character_data_handler(XMLParser $parser, callable $handler): bool

Sets the character data handler function for the XML parser parser.

Parameters

parser

A reference to the XML parser to set up character data 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 two parameters:

handler(XMLParser $parser, string $data)
parser
The first parameter, parser, is a reference to the XML parser calling the handler.
data
The second parameter, data, contains the character data as a string.

Character data handler is called for every piece of a text in the XML document. It can be called multiple times inside each fragment (e.g. for non-ASCII strings).

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.

Changelog

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