run code in 300+ PHP versions simultaneously
<?php class foo { function __toString() { return "bar";}} $a = 12; $b = array(1); $b{2} = 2; var_dump($b);

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).
