# xml_set_character_data_handler

(PHP 4, PHP 5, PHP 7)

xml_set_character_data_handler — Set up character data handler

### Description

xml_set_character_data_handler ( resource `$parser` , callable `$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 ( resource `$parser` , string `$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.
