run code in 300+ PHP versions simultaneously
<?php $a = new DateTime('2014-01-01 22:59'); $b = new DateTime('2014-01-02 01:00'); $diff = $b->diff($a); echo ($diff->h + $diff->days * 24);

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).
