This is not a bug report, but information on upcoming PHP changes that will result in seeing deprecation notices in PHP 8.5 .

See: https://www.zend.com/blog/php-8-5-features under "Resource deprecations".

Calling any of the functions listed there will result in a deprecation message being raised at run-time.

xml_parser_free() is used twice in phpseclib 2.0 at least; I have not checked the other functions or versions.
