First it is not an exception. Secondly, as I said earlier already, this rule is arguable, even more in this particular case. Return NULL when an argument is missing could be fine but to return NULL when an argument cannot be processed is not necessary a good idea. For example: <?php var_dump(is_int($b); ?>, do we want NULL here?
