Bug description: Serialization does not work when I use private/protected members and
__sleep()
Description:
------------
Hello.
I use PHP session. When I use private or protected members in my class and
don't use magic method __sleep(), PHP serialization will serialize all
members and their values into PHP session correctly.
But when I use the same class and implement magic method __sleep(), PHP
serialization will serialize correctly ONLY public members. Private and
protected members (that I want serialize - I specified them in array
returned from __sleep() function) have NULL value.
In my example's result is string from session file generated by PHP.

Reproduce code:
---------------
class Test
{
private $a = "Variable a";
protected $b = "Variable b";
public $c = "Variable c";
public $d = "This need not be saved.";
// Save only $a, $b, $c.
function __sleep()
{
return Array( "a", "b", "c" );
}
}
session_start();
$_SESSION[ "test" ] = new Test();
Expected result:
----------------
test|O:4:"Test":3:{s:7:" Test a";s:10:"Variable a";s:4:" *
b";s:10:"Variable b";s:1:"c";s:10:"Variable c";}
Actual result:
--------------
test|O:4:"Test":3:{s:1:"a";N;s:1:"b";N;s:1:"c";s:10:"Variable c";}
