Class method does NOT delete objects as intended

[garlinto]

In a newly constructed class, I have a method that I want to use to remove any item object where "0 == $item->qty". The item objects are held in an array of objects called "products":

$this->products[$itemid] 

Why will the method below NOT delete the item object with a quantity of zero?

function removeInvalidItems ()
    {
       foreach ( $this->products as $id)
       {
          if ( 0 == $id->qty )
          {
              unset ( $this->$id );
          }
       }
    }

Not positive about the answer without more code but this may be what youre looking for:

function removeInvalidItems() {
    foreach($this->products as $itemId => $product) {
        if ($product->qty == 0)    {
            unset($this->products[$itemId]);
        }
    }
}
