Bug #66739 [Opn->Nab]: strange behavior

Edit report at https://bugs.php.net/bug.php?id=66739&edit=1 ID: 66739 Updated by: nikic@php.net Reported by: temenb at gmail dot com Summary: strange behavior -Status: Open +Status: Not a bug Type: Bug Package: Scripting Engine problem Operating System: ubuntu PHP Version: 5.4Git-2014-02-18 (Git) Block user comment: N Private report: N New Comment: So, what's happen here is this: On PHP 5.x we allow scoped calls to incompatible contexts, by adopting the $this from the incompatible scope. In this instance the A::a1() call in B::b1() will result the $this of A::a1() being the instance of B. If there is a $this, then static:: refers to get_class($this). As such you get a return value of B. In PHP 7.0 we no longer allow calls with incompatible contexts, or rather they are still allowed, but $this will not be bound. As such the result will be A like for a normal static call. So, the behavior is correct for the semantics of the respective PHP versions, even though the 5.x semantics are now obsolete.

In this branch, it returns AAAAAAAA. All other versions return AAAABAAA ------------------------------------------------------------------------ [2014-06-27 12:42:19] pajoye@php.net @ arjen at react dot com phpng is an independent feature branch. We have branches like for 5.4, 5.5, 5.6 or master. Which one do you use? ------------------------------------------------------------------------ [2014-06-27 12:36:24] arjen at react dot com Exact output/warnings @ http://3v4l.org/ek1KG Behaviour changed in 5.7 (phpng). ------------------------------------------------------------------------ [2014-02-19 07:36:02] temenb at gmail dot com Yes. It's true. not obvious. But php allows to call function this way ------------------------------------------------------------------------ [2014-02-19 02:53:53] coolwust at gmail dot com B::b1();//b1 is object method $b->b2();//b2 is static method I think the syntax you calling the method is not correct ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
