Bug #70437 [Opn]: Changes to static properties in trait methods are not reflected in the class

Edit report at https://bugs.php.net/bug.php?id=70437&edit=1 ID: 70437 Updated by: nikic@php.net Reported by: davey@php.net Summary: Changes to static properties in trait methods are not reflected in the class Status: Open Type: Bug Package: Scripting Engine problem Operating System: OSX/Linux PHP Version: 7.0.0RC2 Block user comment: N Private report: N New Comment: Imho the bug here is that we allow calls to static methods on traits. I don't think that's supposed to work and we should add this forgotten check in PHP 7. Previous Comments: ------------------------------------------------------------------------ [2015-09-06 14:32:49] davey@php.net Description: ------------ If you have a trait that defines a static property, and you modify said property from within a trait inherited method, the modifications are done to a trait instance of the property, as opposed to the inherited-from-trait static property within the class. The behavior differs slightly in PHP 5.4.7 - 5.5.29 in that if the methods are instance methods, then they will correctly modify the inherited-from-trait static property, but are broken for static methods. 5.6.0+ has the same behavior for static and instance methods. Test script: --------------- Static methods: https://3v4l.org/UZ6gq Instance methods: https://3v4l.org/piUFm Expected result: ---------------- Should modify the inherited-from-trait static property within the class Actual result: -------------- Modifies a trait-specific copy of the static property ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70437&edit=1
