Operating system: Windows XP
PHP version: 5.2.6
PHP Bug Type: Class/Object related
Bug description: Method hiding/visibility issue
Description:
------------
This issue was brought up in Bug #42830 but the bug was closed as 'Bogus'
but to me it seems to be a valid issue:
I am working on a small framework of my own and all objects share a common
ancestor (base object) that defines __construct as public. I cannot
redefine the visibility of __construct in the base without breaking other
classes, yet I still want this derived, singleton to share the relation.
Addendum: This seems to be the case with any method, actually, not
specific to __construct(). I tried defining a 'GetMessage()' method in the
same class structure.
Reproduce code:
---------------
class BaseObject
{
public function GetMessage() { return "foo1"; }
}
class RequestObject extends BaseObject
{
public function GetMessage() { return "foo2"; }
}
class CurrentRequest extends RequestObject
{
private function GetMessage() { return "top secret"; }
}
Expected result:
----------------
No errors for restricting visibility of methods in derived classes (I can
understand not letting you *increase* visibility of derived methods, but
not the other way around).
Actual result:
--------------
PHP Fatal error: Access level to CurrentRequest::GetMessage() must be
public (as in class RequestObject) in C:\kristian\workspace\guild\foo.php
