run code in 300+ PHP versions simultaneously
<?php namespace Foo; interface Bar {} class Baz implements \Foo\Bar {} $arr = class_implements("\\Foo\\Bar"); var_dump(in_array("\\Foo\\Bar", $arr));

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).
