Note Submitter: ldebuyst->brutele.be ---- In reply to Nikivich and Edorian: Although it isn't quite clear from his post, I believe that the point nicholas is trying to make is that, if you typehint an abstract function, you MUST use that same typehint for all classes extending the abstract class. As his example shows, if you typehint (Object $object), then you must use the exact same typehint in the extending class. Using the typehint (Table $table) or (Chair $chair) will give fatal errors, even if Table and Chair are subclasses of Object. In other words, type hinting allows for descendants, as caliban at darklock dot com has shown, except when you're subclassing. See http://bugs.php.net/bug.php?id=36601 for a bit more info. Flagged as wontfix, though, so something to keep in mind.
