Bug #66719 [Com]: 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 Comment by: coolwust at gmail dot com Reported by: coolwust at gmail dot com Summary: Weird behaviour when using get_called_class() with call_user_func() Status: Open Type: Bug Package: Class/Object related Operating System: linux PHP Version: 5.5.9 Block user comment: N Private report: N New Comment: 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.

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. ------------------------------------------------------------------------ [2014-02-15 18:28:53] coolwust at gmail dot com Description: ------------ --- From manual page: http://www.php.net/function.get-called-class --- B::who(); should has the same result as call_user_func(array('B', 'parent::who')); But it's not. See the example below. Test script: --------------- <?php class A { public static function who() { var_dump(get_called_class()); } } class B extends A { public static function who() { parent::who(); } } B::who(); call_user_func(array('B', 'parent::who')); ?> Expected result: ---------------- string 'B' (length=1) string 'B' (length=1) Actual result: -------------- string 'B' (length=1) boolean false ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66719&edit=1
