run code in 300+ PHP versions simultaneously
<?php for ($i=0; $i < 100; $i++) { echo genRand(); } public function genRand(){ return mt_rand(1, 500); }

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).
