run code in 300+ PHP versions simultaneously
<?php namespace Foo { class Bar {} } namespace Qux { $foo = new \Foo\Bar; $foo = new Bar; $foo = new FBar; use Foo\Bar; use Foo\Bar as FBar; }

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).
