run code in 300+ PHP versions simultaneously
<?php function get_age() { $now = new DateTime(); return $now->diff(new DateTime('1989-01-14'))->; } echo get_age();?>

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).
