run code in 300+ PHP versions simultaneously
<?php spl_autoload_register(function($classname) { if (in_array($classname, array('a','b','c'))) { require_once ($classname . '.php'); } }); set_error_handler(function ($errno, $errstr, $errfile, $errline) { }, error_reporting()); a::staticTest(); $b = new b(); $b->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).
