run code in 300+ PHP versions simultaneously
<?php class A { protected static $modules; } class B extends A { public static $modules; public function __construct() { echo 'Hello B'; } } $x = new B();

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).
