run code in 300+ PHP versions simultaneously
<?php class c { function test() { c::x(); } static function x() { var_dump(isset($this)); } }; $x = new c; $x->test();

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).
