run code in 300+ PHP versions simultaneously
<?php namespace b { class my_class{ function test() { echo 'here'; } } } namespace a { use b as c; // FQN (new \b\my_class())->test(); // Aliased (new c\my_class())->test(); }

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).
