Type hints were first and foremost introduced for object oriented safety, as a part of the major OO model shift Andi and I pushed for in PHP 5.0. What you may be alluding to - type hints for arrays and objects - were added at later time and introduced that small inconsistency you're talking about. Still, type juggling for scalars has been the fundamental nature of PHP since the get go; Type jugging for arrays/objects was always more of an edge case and perhaps even a misfeature. > You can be consistent with casts, or consistent with existing type hints, > but not > both. Type looseness defines PHP. Type hints do not. Zeev -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
