run code in 300+ PHP versions simultaneously
<?php $a = array(); $a[] = 1; $a[] = 2; $a[] = 3; foreach ($a as $key => $row) { print $a.'\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).
