run code in 300+ PHP versions simultaneously
<?php class A { public $a = ''; } class B { public $a = ''; } var_dump(md5(serialize(new A())) === md5(serialize(new A())));

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).
