run code in 300+ PHP versions simultaneously
<?php $a = 1; $b = 1; for ($i = 0; $i <= 100; $i++) { list($a, $b) = array($b, $a + $b); echo $b . PHP_EOL; }

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).
