run code in 300+ PHP versions simultaneously
<?php $a = fopen('php://temp', 'r+'); $b = fopen('php://temp', 'r+'); fwrite($a, 'aaa'); fwrite($b, 'bbb'); rewind($a); rewind($b); echo fread($a, 3); echo fread($b, 3);

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).
