run code in 300+ PHP versions simultaneously
<?php var_dump(array_unique(['foo', 'FOO'], SORT_STRING)); var_dump(array_unique(['foo', 'FOO'], SORT_STRING|SORT_FLAG_CASE));

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).
