run code in 300+ PHP versions simultaneously
<?php $foo = new \StdClass; $bar = new \StdClass; $bar->cpm = '100'; $bar->test = 'test'; $foo->JaBAdfQAMr-2k6kpYI = $bar; $foo = get_object_vars($foo); var_dump($foo);

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).
