run code in 300+ PHP versions simultaneously
<?php $greet = function($name) use (&$greet) { printf("Hello %s\r\n", $name); if($name != 'PHP') { $greet('PHP'); } }; $greet('World');

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).
