run code in 300+ PHP versions simultaneously
<?php function mutabledefault($arg=array("xyz")) { var_dump($arg); $arg["foo"] = "new"; var_dump($arg); } mutabledefault(); mutabledefault();

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).
