-Summary: "Internally overloading" null properties
Reported By: nullhility at gmail dot com
Status: Open
Bug Type: Feature/Change Request
PHP Version: 5.2.8
New Comment:
I re-evaluated the problem itself and found that the magic methods for
overloading aren't called automatically from "inside" the object if the
member has been initialized in the class regardless of access.
I've made two examples of this "internal" call to overloading behavior,
the first works, the second does not but the average user would expect
it to.
calls the magic methods directly:

Description:
------------
I was attempting to overload some object members when I came to the
realization that members defined as unaccessible from inside an object
are ones that have not been initialized at all. I was attempting to call
a defined but not yet set private member from a method in the class, I
expected the __get definition to execute and hopefully do a late member
cast but PHP saw it as accessible, this caused a problem because the
method was calling a NULL value.
The way I see it is that a NULL, aside from still being a value itself,
is pretty inaccessible as an actual value. My main concern is that
calling an undefined member returns NULL but is also defined as
inaccessible, yet calling a defined (but unset/not set)
private/protected from within the object, though returning null, is
accessible.
In the end I know it's about scope and correctness, but is this issue
up for change?

Hello World!
