run code in 300+ PHP versions simultaneously
<?php namespace foo { class Xyz {} function abc () {} } namespace bar { use foo\Xyz as x; class Xyz {} var_dump(new Xyz()); // instantiates \foo\Xyz } ?>

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).
