Regarding PDO's fetch(PDO::FETCH_CLASS) method...

[Hall of Famer]

Well lets say I have a class called Private_Item with a property like $owner. The class itself and constructor will look like the way below: (Note the Private_Item class extends from a parent class called Item, this is not to be worried here)

 

class Private_Item extends Item{
   private $iid;
   // The itemname and category properties already exist for parent class
   private $owner;
   private $quantity;
   private $status = "Available";

   public function __construct($name, $owner, $quantity){
       parent::__construct($name);
       $this->owner = new User($owner);
       $this->quantity = $quantity;
   }
}  

 

Whenever I define a variable like $item = new Private_Item($itemname, $itemowner, $quantity), the $itemowner is used as reference to instantiate a User object, and then passed to the property $this->owner. In this way, I have actually instantiated two objects at once. One for the item, the other for the user who owns this item.

 

I have a question about using PDO's fetch class method though. I'd like to use it to retrieve database info and instantiate a Private_Item object immediately after fetching it from MySQL database. The code looks like below:

 

$item = $stmt->fetch(PDO::FETCH_CLASS, "Private_Item");

 

The real question is, can the user object still be instantiated in the meantime? I am not quite sure about this, and I may end up having only one $item object but its property $item->owner is not. For those of you familiar with advanced PDO stuff, please lemme know if I can instantiate a subsequent object with the method fetch(PDO::FETCH_CLASS). Thanks.
