run code in 300+ PHP versions simultaneously
<?php $n = array(1, 3); $k = 0; $x = 1; echo "$x\n"; for ($i = 1; $i < 300; $i++) { $x += $n[$k]; if ($k == 0) $k = 1; else $k = 0; }

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).
