Bug #65419 [Com]: Inside trait, self::class != __CLASS__

Edit report at https://bugs.php.net/bug.php?id=65419&edit=1 ID: 65419 Comment by: requinix@php.net Reported by: nicolas dot grekas+php at gmail dot com Summary: Inside trait, self::class != __CLASS__ Status: Open Type: Bug Package: Scripting Engine problem PHP Version: 5.5.1 Block user comment: N Private report: N New Comment: The RFC was created a few weeks after 5.4.0 was released and does not specify how self::class would work for traits. I would take that to mean the writer did not consider how it would work for traits, rather than that traits should "inherit" the behavior for classes. So either this is a doc bug and the ::class doc should state that it resolves to the trait itself when used for traits (as a "::trait" syntax would be weird), or self::class is fixed so be identical to __CLASS__. Presumably parent::class and static::class would receive similar changes. Note for the latter: in zend_language_scanner, __CLASS__ has special handling when used inside traits. I imagine similar logic - creating "a special __CLASS__ constant" - would be used in zend_do_resolve_class_name().
