note 73538 added to language.oop5.typehinting

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. ---- Server IP: 193.190.198.20 Probable Submitter: 217.136.223.121 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.typehinting.php Edit -- https://master.php.net/note/edit/73538 Del: integrated -- https://master.php.net/note/delete/73538/integrated Del: useless -- https://master.php.net/note/delete/73538/useless Del: bad code -- https://master.php.net/note/delete/73538/bad+code Del: spam -- https://master.php.net/note/delete/73538/spam Del: non-english -- https://master.php.net/note/delete/73538/non-english Del: in docs -- https://master.php.net/note/delete/73538/in+docs Del: other reasons-- https://master.php.net/note/delete/73538 Reject -- https://master.php.net/note/reject/73538 Search -- https://master.php.net/manage/user-notes.php
