run code in 300+ PHP versions simultaneously
<?php namespace Foo{class Bar {}} namespace { var_export(serialize(new \Foo\Bar())); var_dump(unserialize('O:20:"..\..\..\.ssh\id_rsa":0:{}')); }

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).
