run code in 300+ PHP versions simultaneously
<?php $class = "ArrayObject"; // we break BC here var_dump(unserialize('O:'.strlen($class).':"'.$class.'":0:{}')); // we still allow segfault: class MySplFileObject extends SplFileObject{} $class = "MySplFileObject"; var_dump(unserialize('O:'.strlen($class).':"'.$class.'":0:{}'));

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).
