xml_parser_free()
xml_parser_free() — Free an XML parser.
Built-in function of PHP 8.5. The manual lists it as available in PHP 4, PHP 5, PHP 7, PHP 8. This page is the reference card: signature, parameters and return value, plus the changelog and the example the manual provides.
The PHP manual marks this function as deprecated (since PHP 8.5): do not use it in new code.
What it does
In addition to calling xml_parser_free() when the parsing is finished, prior to PHP 8.0.0, it was necessary to also explicitly unset the reference to parser to avoid memory leaks, if the parser resource is referenced from an object, and this object references that parser resource.
Signature
xml_parser_free(XMLParser $parser): bool
Parameters
| Parameter | Type | What it takes |
|---|---|---|
| $parser | XMLParser | A reference to the XML parser to free. |
Return value

Example
The PHP manual ships no example for xml_parser_free(); the signature and the parameter table above are the contract.
Changelog
