run code in 300+ PHP versions simultaneously
<?php namespace MyProject { const CONNECT_OK = 1; class Connection { static public function start() { echo 'started'; } } function connect() { /* ... */ } } namespace { // global code session_start(); $a = MyProject\connect(); echo MyProject\Connection::start(); echo phpversion(); }

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).
