Edit report at https://bugs.php.net/bug.php?id=63911&edit=1 ID: 63911 Updated by: gron@php.net Reported by: bitluni at bitluni dot net Summary: Ignore conflicting trait methods originationg from identical sub traits -Status: Open +Status: Verified -Type: Feature/Change Request +Type: Bug Package: Class/Object related Operating System: debian PHP Version: 5.4.10 Block user comment: N Private report: N New Comment: This is indeed a bug. Unfortunately, this case slipped and did not get tested. It is a perfectly valid usecase, and should not require the use of insteadof at all. Best regards Stefan Previous Comments: ------------------------------------------------------------------------ [2013-09-15 17:23:42] heruan at aldu dot net insteadOf in this case is just a workaround, since there is nothing to 'use instead of' something else because here there is a property/method conflicting with its very self! And BTW insteadOf cannot be used as a workaround with properties. ------------------------------------------------------------------------ [2013-05-03 10:26:44] simon at simon dot geek dot nz This is still occurring with PHP 5.5, commit cbe2870b72c4cfdb5c295e83c88d7cff5c39e396 (Fri May 3 12:25:49 2013 +0400). Not being able to use multiple traits that have the same trait somewhere in their composition trees is a rather major limitation of the trait system. ------------------------------------------------------------------------ [2013-01-06 10:31:40] bitluni at bitluni dot net @necktrox I know there is 'insteadof' but see my example, there is just one function implemented yet still I get collision error. The traits are just usable very flat at the moment. If you have an hirachical stucture of traits like I do, you have to do potentally exponetial count of 'insteadof's in the top level class even there's not one dublicate function implemented. ------------------------------------------------------------------------ [2013-01-06 02:36:02] necktrox at gmail dot com # from http://php.net/manual/de/language.oop5.traits.php trait A { public function smallTalk() { echo 'a'; } public function bigTalk() { echo 'A'; } } trait B { public function smallTalk() { echo 'b'; } public function bigTalk() { echo 'B'; } } class Talker { use A, B { B::smallTalk insteadof A; A::bigTalk insteadof B; } } ------------------------------------------------------------------------ [2013-01-05 18:39:11] bitluni at bitluni dot net same issue for properties ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
