xml_set_object — Use XML Parser within an object

Warning

This function has been DEPRECATED as of PHP 8.4.0. Relying on this function is highly discouraged.

### Description

#[\Deprecated]
xml_set_object(XMLParser `$parser`, object `$object`): true

This function allows to use `parser` inside `object`. All callback functions could be set with xml_set_element_handler() etc and assumed to be methods of `object`.

### Parameters

`parser`

  A reference to the XML parser to use inside the object.

`object`

  The object where to use the XML parser.

### Return Values

Always returns `true`.

### Changelog

Version | Description
--- | ---
8.4.0 | This function is now deprecated, instead pass proper callable values to xml_set_()
8.0.0 | `parser` expects an XMLParser instance now; previously, a valid `xml` resource was expected.

### Examples

Example #1 xml_set_object() example

    <?php
    class CustomXMLParser
    {
        private $parser;

        function __construct()
        {
            $this->parser = xml_parser_create();

            xml_set_object($this->parser, $this);
            xml_set_element_handler($this->parser, "tag_open", "tag_close");
            xml_set_character_data_handler($this->parser, "cdata");
        }

        function parse($data)
        {
            xml_parse($this->parser, $data);
        }

        function tag_open($parser, $tag, $attributes)
        {
            var_dump($tag, $attributes);
        }

        function cdata($parser, $cdata)
        {
            var_dump($cdata);
        }

        function tag_close($parser, $tag)
        {
            var_dump($tag);
        }
    }

    $xml_parser = new CustomXMLParser();
    $xml_parser->parse("<A ID='hallo'>PHP</A>");
    ?>

The above example will output:

    string(1) "A"
    array(1) {
      ["ID"]=>
      string(5) "hallo"
    }
    string(3) "PHP"
    string(1) "A"
