Edit report at https://bugs.php.net/bug.php?id=61943&edit=1 ID: 61943 Updated by: gron@php.net Reported by: franssen dot roland at gmail dot com Summary: Trait same property conflict in class extending Status: Open Type: Feature/Change Request Package: Scripting Engine problem Operating System: Ubuntu PHP Version: 5.4.2 -Assigned To: +Assigned To: gron Block user comment: N Private report: N New Comment: Hi: From my point of view, it is not the same property. My understanding is that you are moving here very much in the area of the typical diamond problem of multiple inheritance. Theoretically, it is not clear whether the two properties should be handled as the same or not. Why would you want to apply the trait a second time? Best regards Stefan Previous Comments: ------------------------------------------------------------------------ [2012-05-04 20:07:42] franssen dot roland at gmail dot com Description: ------------ Hi, (version is actually 5.4RC9...) The same property conflict happens when you have 2 traits (B uses A) where A defines the property, class Foo uses A and class Bar uses B _and_ extends Foo. I would love to see the strict standard to be removed in this situation; how can a property have a conflict with itself? Test script: --------------- <?php trait A { public $prop; } trait B { use A; } class Foo { use A; } class Bar extends Foo { use B; } Expected result: ---------------- <void> Actual result: -------------- Strict Standards: Foo and B define the same property ($prop) in the composition of Bar. This might be incompatible, to improve maintainability consider using accessor methods in traits instead. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61943&edit=1
