Expect same behavior as array_diff() http://de.php.net/manual/en/function.array-
diff.php

Well, some may want - to behave like array_diff(), others as
array_diff_assoc(), and others as array_diff_key().  I'm not even
sure which one I'd prefer, but I'm fine with being explicit, and
rather avoid thinking about it.

If you stll feel this would be a valuable addition to PHP, please
pursue the RFC process[1].
