run code in 300+ PHP versions simultaneously
<?php class A { protected $a = 'a'; } abstract class B extends A { protected $b = 'b'; } class C extends B { protected $c = 'c'; } $c = new C(); var_dump($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).
