One issue with PHP 8.2+ as far as I can tell, is that in Dev mode some pages act funny, with a bunch of our plugins that use the apparently standard IPB construct 'return \call_user_func_array( 'parent::' . __FUNCTION__, \func_get_args() );', throwing deprecation and Exceptioning out of most pages.
You can of course disable deprecations in php.ini (```error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT```)
But then the 'get support' page doesn't load, unless you hack some PHP code like this into the top of the core support.php file (```error_reporting(E_ALL | E_STRICT);```). It's possible that under 8.2 / dev / prod mode it's also throwing other errors.
Finding a php.ini error_reporting config that works for both use cases does not seem to exist. Looking forward to PHP 8.2 support soon.
