What is the best way to fill an object with data from a database

Hi all

What is the best way to fill an array objects with data from a database

My code

PHP Code:

class ProductsContentComposite extends AbstractContentComposite {
    public function addElement(InterfacePrototype $element)
    {
        $this->elements[] = $element;
    }
} 


In Controller

PHP Code:

$productsComposite = new ProductsContentComposite();
/* some logic */
$results = $this->product_model->getAll();
$productPrototype = new ProductContentPrototype();
/* some logic */
foreach ($results as $result)
{
$clonePrototype = clone $productPrototype;
/* some logic */
$productsComposite->addElement($clonePrototype);
} 


Is this the right way or not?
