well, i guess its ok then, its just not what im used to with some other
languages
but i still think its wierd using protected to "protect" the data from
the outside world, but not quite doing so.
i now know storing vital information such as passwords inside class
variables even protected ones, doesnt help much.
so giving another developer access to an api doesnt protect me anymore
either
but if its no bug since changing the data isnt possible that way, so be
it.
and i have to say dont change the point:
first you say its about visibility,
i explain why it is,
next you say it doesnt matter because you cant change its value

Yes, but can you _change_ it? (answer: no, not via that array..)

I think the bug is that I CAN access private / protected class data at
runtime which neglects the whole point of private or protected data
inside classes. It is to be protected!
Why else use private data if you can access it anyway? its useless
then. its just obstruction instead of security. (security in terms of
data integrity)
On the positive side at least i can not change the data.
And to refer to your reaction precisely, lets have two classes A and B
A is instanciated and has a private property x which is set, class B
casts class A to an array and gains access to class A's private property
x. This is not directly about visibility but it allows class B to "view"
class A's private property x.

Private/protected is about visibility between _classes_ not with a
class cast to an array. So what's the "bug" here?

Description:
------------
Hello dear developer(s),
When i setup a simple class with a protected/private var,
instanciate the class, and cast the instance to an array
i can access the protected/private var.
Reproduce code:
---------------
class test {
public $public = 'public';
private $private = 'private';
protected $protected = 'protected';
}
$t = new test;
$a = (array)$t;
print '<br>public: '.$a['public'];
print '<br>private: '.$a["\0test\0private"];
print '<br>protected: '.$a["\0*\0protected"];
Expected result:
----------------
Expected:
public: public
Or at most an Error like:
Cannot access private property test::$private
as the value of the private property
Actual result:
--------------
Result:
public: public
private: private
protected: protected
------------------------------------------------------------------------
