run code in 300+ PHP versions simultaneously
<?php function nek($fek) { if($fek = 0) { return $fek; } else { return nek($fek) + nek($fek--); } } echo nek(6);

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).
