Problem with object cloning in PHP5

[mrfree]

When I clone an istance of System class I want to clone all SubSystem istances in $subsystems array too, so I tryed with this code

class System {
    public $name;
    public $subsystems = array();

function __construct($name){
   $this->name = $name;
}

function __clone(){
    foreach( $this->subsystems as $key => $item ){
       $this->subsystems[$key] = clone($this->subsystems[$key]);
    }
}
 }

 class SubSystem {
    public $name;
    public $type = 2;
    public $skip_AP_search = false;

function __construct($name){
   $this->name = $name;
}
 }

But when I clone...

--- var_dump($orig->subsystems);

array(1) {
  [0]=>
  &object(SubSystem)#12 (7) {
    ["name"]=>
    string(4) "sub1"
    ["type"]=>
    int(2)
    ["skip_AP_search"]=>
    bool(false)
  }
}

--- var_dump($copy->subsystems);

array(1) {
  [0]=>
  &object(SubSystem)#12 (7) {
    ["name"]=>
    string(4) "sub1"
    ["type"]=>
    int(2)
    ["skip_AP_search"]=>
    bool(false)
  }
}

So the istances in the arrays are the same 🙁

What's wrong?
