run code in 300+ PHP versions simultaneously
<?php class Test { protected $attr = null; } $test = new Test(); $test2 = base64_encode(serialize($test)); var_dump((bool) '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).
