Description:
------------
I'm developing an OOP FrameWork and i'm improving ActiveRecord. My AR class 
extends from ArrayObject Class from PHP and when i try to set an AR Object into 
another, mixing the _data array between normally vars and an AR, PHP crushes and 
server crash.

If i do this:

class ActiveRecord extends ArrayObject{
  public function __set($name, $value) {
	$this->_data[$name] = $value;
  }
}

class A extends ActiveRecord{
  public function __construct(){
  }
}

class B extends ActiveRecord{
  public function __construct(){
  }
}

$A = new A;
$B = new B;

$A->foo = 3; // everything alright, no crushes.
$B->var = 4; // everything alright, no crushes.

$B->A = $A; // Crush!!!!

When i tried this, the server goes down, but i figured out to use another array 
for the AR objects apart from the $_data array and its works.

This works:


public function __set($name, $value) {
  if(is_object($value) and strcmp(get_parent_class($value),'ActiveRecord')===0):
    $this->_models[$name] = $value;
  else:
    $this->_data[$name] = $value;
  endif;
}


So, why does it happens??

I can not use P.H.P. > 5.2.9 beecause the server is not mine and its a paid 
server. I have to fix to this requirement.
