run code in 300+ PHP versions simultaneously
<?php $date1 = "2007-03-24"; $date2 = "2009-06-26"; $diff = abs(strtotime($date2) - strtotime($date1)); $days = floor($diff / 60*60*24); printf("%d days\n", $days);

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).
