run code in 300+ PHP versions simultaneously
<?php class A { public function __construct() { } } class B extends A { } class C extends B { public function __construct() { parent::__construct(); } } $c = 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).
