Object Serialize

Hi,
I want to serialize my object recursively.
How can i complete this job?
ps: i use serialize but it does't serialize Area object in $areaList array of course.

<?php
class Design{
	public $areaList=array();
	function __construct(){}
	function __destruct(){}
	
	function newArea(){
		$area=new Area(null);
		$this->areaList[sizeof($this->areaList)]=$area;
		return $area;
	}
}
 
class Area{
	public $className="";
	protected $areaId="";
	protected $parentArea=null;
	protected $subAreaCount=0;
	protected $areaObject=null; //Form
 
	function getHTML($newRow=false){
		if ($newRow==true)
			$className="newrow";
		else
			$className="newArea col";
		
		$areaId="area_".uniqid();
		$responseStr="<div id='$areaId' class='$className'></div>|";
		$responseStr.="{areaId:'$areaId'}";
		return $responseStr;
	}
	
	function __construct($parentArea){
		$this->parentArea=$parentArea;
	}
	
}
?>
another page
<?php
  $design=new Design();
  $newArea=$design->newArea();
  $_SESSION["Design"]=serialize($design); //this is just serialize Design object. Not area objects in Design object
 
?>

hmm...
The solution is for another trouble but seems to work.
It think that the autoload is better for a simple reason. All data will be in the Server Side so, why transfer a lot of data between Client/Server?
Whit code above you can put into a general include header and at any time do this
<?php
$to_save['var_name']=$var_name;
$to_save['ObjectName']=$ObjectName;
?>

But, Objects that point to another Object or is extended from another class need that the parent or pointed classes available and the solution is __autoload function (a magic function);

Its almost a persistance like JAVA do (I said almost).
Some vars cannot be saved this way (or any other way) like resources (any kind).

The code below is a snipplet that create the main mecanism to use this kind of persistance.
The function __autoload above complete the code.

<?php
  function serializeVars(){
    if(isset($GLOBALS['to_save'])){
        $_SESSION['saved_vars']=serialize($to_save);
    }
  }
 
 // When script ends call this function
 register_shutdown_function(serializeVars'');
 
  // a general session start 
  if(session_id()==""){
     session_start();
  }
  if(isset($_SESSION['saved_vars'])){
     extract($_SESSION['saved_vars']);
     // now all saved Vars, including arrays and Objects in the session will be available again
  }  
  $to_save=arary();
?>
