run code in 300+ PHP versions simultaneously
<?php $a = array(); for($i=0;$i<10000;$i++) { $a = strtolower(strtoupper(implode(array_merge($a, range("a", "z"))))); }

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).
