run code in 300+ PHP versions simultaneously
<?php $a =[[1],[2],[2],[4],[5],[5],[3]]; Foreach($a as $b){ Echo $b[0]. "\n"; If(next($a)[0] != $b[0]) echo "\n"; }

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).
