run code in 300+ PHP versions simultaneously
<?php $a = [1, 2, 3]; $limit = 10; foreach ($a as &$v) { array_push($a, 'x'); var_dump($a); if (--$limit == 0) break; }

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).
