run code in 300+ PHP versions simultaneously
<?php namespace foo { class foo1 { } } namespace bar { class foo2 { } } namespace { $f = new "\foo\foo1"(); var_dump($f); $f = new "\bar\foo1"(); var_dump($f); }

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).
