run code in 300+ PHP versions simultaneously
<?php $a = array(0,1,2,3,4,5); $b = array(0,1,2,3,4,5); foreach($a as $aa) { foreach($b as $bb) { if ($aa == $bb) continue; if ($aa > $bb) continue 2; echo "$aa -> $bb"; } }

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).
