run code in 300+ PHP versions simultaneously
<?php namespace foo { class false {} } namespace bar { use foo\false; $a = new false(); var_dump($a instanceof false); }

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).
