run code in 300+ PHP versions simultaneously
<?php $foo = new stdClass(); $bar = 'bar'; $foo->$bar = array(); // works as expected var_dump($foo); //$foo->$bar[] = 'baz'; // oops

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).
