run code in 300+ PHP versions simultaneously
<?php namespace Foo; define('Foo\\true', 'lolphp'); echo 'true: '; var_dump(true); echo '\\true: '; var_dump(\true); echo 'TRUE: '; var_dump(TRUE);

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).
