run code in 300+ PHP versions simultaneously
<?php class Foo { private static function bar($t) { var_dump ($t);} } function &baz() { } unset(bar()); var_dump(function_exists(['Foo', 'bar']));

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
