run code in 300+ PHP versions simultaneously
<?php $a = "2008-01-01"; $b = "2008-01-15"; $i = date("Y-m", strtotime($a)); while($i <= date("Y-m", strtotime($b))){ echo $i."\n"; if(substr($i, 4, 2) == "12") $i = (date("Y", strtotime($i."01")) + 1)."01"; else $i++; }

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).
