run code in 300+ PHP versions simultaneously
<?php class P { function __construct() { echo 'sssss'; } function p() { echo 'sssss'; } } class C extends p { function __construct() {} function d() {} } new c;

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).
