run code in 300+ PHP versions simultaneously
<?php namespace Foo { class A {} } namespace Bar { use Foo\A as Baz; $x = new \Foo\A; $y = new Baz; var_dump($x); var_dump($y); }

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).
