Maybe it is not valid to have private variables of parent class in
Reflection. Then it is only my own custom serialization problem.

------------------------------------------------------------------------

[2006-08-20 12:39:18] ruslan dot kyrychuk at gmail dot com

With this serializing interface (if you mean __sleep and __wakeup
method) and with reflection can not work with private variables, I can
not write serialization method that can be used in all child classes .In
every child class Reflection will have child instance and will not have
access for private variables of parent. 

Reproduce code:
---------------
class A
{
        public function __sleep() 
        {
                $refl = new ReflectionObject($this);
                $props = $refl->getProperties();
                $result = array();
                foreach($props as $prop)
                        $result[] = $prop->getName();
                return $result ;
        }
        private $privateVar = 'Test Private';
        public $publicVar = 'Test Public';
        
        public function setPublic($value)
        {
                $this->publicVar = $value;
        }
        public function setPrivate($value)
        {
                $this->privateVar = $value;
        }
}

class B extends A{}

$instance = new B();
$instance->setPrivate('Set Test Private');
$instance->setPublic('Set Test Private');

var_dump($instance);
var_dump(unserialize(serialize($instance)));

Expected result:
----------------
Object before serializing and after is same.

Actual result:
--------------
object(B)#1 (2) {
  ["privateVar:private"]=>
  string(16) "Set Test Private"
  ["publicVar"]=>
  string(16) "Set Test Private"
}
object(B)#3 (2) {
  ["privateVar:private"]=>
  string(12) "Test Private"
  ["publicVar"]=>
  string(16) "Set Test Private"
}


--------------
When writing 
public function __sleep(){return array('privateVar', 'publicVar');} In
B class
Than you'll get 

Notice: serialize() [function.serialize]: "privateVar" returned as
member variable from __sleep() but does not exist.

So you can't write custom serializing for child object when private
properties exists in parent class.

------------------------------------------------------------------------

[2006-08-20 11:07:59] [EMAIL PROTECTED]

That is why we have a new serializing interface which allows you to
call a serializing function in the base class which then can deal with
the private properties in that base class.

------------------------------------------------------------------------

[2006-08-20 09:31:05] ruslan dot kyrychuk at gmail dot com

I'd say it is not correct. Properties and methods defined as private
are inherited but you have no access to this properties in child class.
If for example during serializing if you ommit private properties of
base class - you'll get wrong object.

class Base{
  private $basevar;
  public function baseFunction(){return $this->basevar;}
}
class Derived extends Base{}

if private properties are not inherited - than calling baseFunction
will cause null result and this is not correct in class inheritance.
