run code in 300+ PHP versions simultaneously
<?php var_dump((object) ["\x00key" => "value"]); var_dump(unserialize(serialize((object) ["\x00key" => "value"])));

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).
