Subject: need inverted __sleep?
From: nrixham@gmail.com (Nathan Rixham)

Hi All,

hoping somebody can help me here..

I need to implement an inverted __sleep method, by which I mean to 
specify what variables should not be included.

use case:
<?php
class base
{
   private $notToBeSerialized;

   public function __sleep()
   {
     // TODO code return instance properties excluding $notToBeSerialized
   }

}

class foo extends base
{
   private $bar;
}

class poo extends foo
{
   private $baz;
}

$p = new poo;
echo serialize($p);

----

I've tried using get_object_vars($this), and ReflectionObject($this) 
both of which don't include all the properties of the instance.

the only way I can see to get all the properties of the instance is to 
serialize($this) then parse the string, but that's just wrong and what 
would sleep return on the first call to serialize.

any help greatly appreciated.

regards,

nathan
