Bug #66719 [Opn->Ver]: Weird behaviour when using get_called_class() with call_user_func()

Edit report at https://bugs.php.net/bug.php?id=66719&edit=1 ID: 66719 Updated by: cmb@php.net Reported by: coolwust at gmail dot com Summary: Weird behaviour when using get_called_class() with call_user_func() -Status: Open +Status: Verified Type: Bug Package: Class/Object related Operating System: linux PHP Version: 5.5.9 Block user comment: N Private report: N New Comment: The example calls this feature "relative static class method call", and as such it should behave identically to calling A::who() directly, but it doesn't: <https://3v4l.org/vbuVd>. Interestingly, calling the callable $method directly fails completely. Previous Comments: ------------------------------------------------------------------------ [2014-02-16 01:41:22] coolwust at gmail dot com here is a new little test snippet: class A { public static function who() { $obj = new static; var_dump($obj); } } class B extends A { public static function who() { parent::who(); } } B::who(); //output object(B)[1] call_user_func(array('B', 'parent::who')); //output Fatal error: Cannot access static:: when no class scope is active This means get_called_class() does it job correctly, as it is out of scope and returns null. However, the doc should gives more details on "parent::who" ------------------------------------------------------------------------ [2014-02-16 01:27:01] coolwust at gmail dot com I was thinking it should output B, but yea, you are right, it simply means B's parent who, but doesn't mention the calling scope. The documentation should show more details on parent::who, what exactly it means. ------------------------------------------------------------------------ [2014-02-16 00:00:57] requinix@php.net Interesting. I had no idea that feature existed. Just checked with 5.5.6 and it has the same behavior. Looks like a bug then as it's not showing any class at all. However I'm not sure which class it should show: could be A if it resolved as B::parent's who, or it could be B if it resolved as B and then parent::who. ------------------------------------------------------------------------ [2014-02-15 22:44:18] coolwust at gmail dot com According to http://us1.php.net/manual/en/language.types.callable.php It is valid: // Type 5: Relative static class method call (As of PHP 5.3.0) class A { public static function who() { echo "A\n"; } } class B extends A { public static function who() { echo "B\n"; } } call_user_func(array('B', 'parent::who')); // A ------------------------------------------------------------------------ [2014-02-15 21:40:56] requinix@php.net array('B', 'parent::who') is not valid: the second element must be the name of a method. array('B', 'who') is the correct form. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
