ID: 55524 Updated by: g...@php.net Reported by: g...@php.net Summary: Traits should not be able to extend a class -Status: Open +Status: Assigned Type: Bug Package: Scripting Engine problem PHP Version: 5.4.0alpha3 -Assigned To: +Assigned To: gron Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2011-08-28 08:05:04] g...@php.net Description: ------------ Spotted by this post: http://zuttonet.com/articles/php-class-traits/ Traits build their own hierarchy of uses, but there is no useful semantics for extending classes. For instance: trait Foo extends Base { function bar() {} } The semantics for that is not defined (and actually at least broken for abstract methods). This should give a fatal error as would the other way around (Base extends Foo). Test script: --------------- trait Foo extends Base { function bar() {} } Expected result: ---------------- Fatal error: A trait (Foo) cannot extend a class (Base) in %s on line %d ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55524&edit=1
