run code in 300+ PHP versions simultaneously
<?php $r = range(1,10); array_walk($r, function(&$value, $key) { $double = $value*2; if ($double >= 12) { $value = $double; } else { unset($value); } echo $double, PHP_EOL; }); var_dump($r);

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).
