run code in 300+ PHP versions simultaneously
<?php $fn = create_function( '$x', 'return $x; } $foo =''; function foo($int) { return $int; ' ); echo foo($fn($foo));

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).
