That is why I suggested, in addition to the above, a syntax like: function (Foo | NULL) foo($something) { to be able to specify where a function can return more than one type. The 'extra' types/values are nearly always either NULL or FALSE. I agree that being able to specify as types: array, scalar, int, string, ... would be useful for a compiler but prob have little value for Zend - other than documentation/reflection. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.
