run code in 300+ PHP versions simultaneously
<?php if(!function_exists('function_exists')) { function function_exists($f) { return function_exists($f); } }

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).
