Bug #52245 [Opn->Bgs]: Private member of parent class accessible from child class.

Edit report at http://bugs.php.net/bug.php?id=52245&edit=1 ID: 52245 Updated by: johannes@php.net Reported by: phpamid at gmail dot com Summary: Private member of parent class accessible from child class. -Status: Open +Status: Bogus Type: Bug Package: *General Issues Operating System: Windows 7 x64 PHP Version: 5.3.2 New Comment: You are calling show_private_member(). That method belongs to Father and therefore has access to Father's private elements. The method has no access to other class's private elements. Are you looking for protected elements? Previous Comments: ------------------------------------------------------------------------ [2010-07-04 15:11:05] phpamid at gmail dot com as for your code: class A { private $a = "a"; } class B extends A { private $a = "b"; // is this an error? } i think every class has own private member, so there is no error. -------------------------------------------------------------------- Ok, I got you. I hope that this issue will be clarified. Thank you for discussion. ------------------------------------------------------------------------ [2010-07-04 14:32:12] giorgio dot liscio at email dot it in fact if you use protected instead of private it works as expected but the "private" issue should be clarified, i think * i'm sorry for the second post ------------------------------------------------------------------------ [2010-07-04 14:26:04] giorgio dot liscio at email dot it sure i know i don't need to override the method with the same one in the new class to fix this problem in the parent class the field is private... so theoretically i can not access the member in the derived class class A { private $a = "a"; } class B extends A { private $a = "b"; // is this an error? } it probably is, and maybe php should throw an error ------------------------------------------------------------------------ [2010-07-04 14:00:51] phpamid at gmail dot com ......... class Son extends Father{private $x = 'SON'; // try to decomment this: //public function a(){echo $this->x;} } ............. I know if I override method a() in the child - everything will be ok, but it's not necessary to override method a(), because method a() is inherited form father class and it's public. p.s. if it's a bug, then it's php behavior. ------------------------------------------------------------------------ [2010-07-04 13:50:26] giorgio dot liscio at email dot it i think that is a bug but i'm not sure if is a php behavior <?php class Father{private $x = 'FATHER'; public function a(){echo $this->x;} } class Son extends Father{private $x = 'SON'; // try to decomment this: //public function a(){echo $this->x;} } $son_instance = new Son; $son_instance->a(); ?> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
