This
$item = $em->getReference('Item', $id);
$cart->addItem($item);
has better performance than this?
$item = $em->find('Item', $id);
$cart->addItem($item);
Please advice.
It is a bit faster (assuming you don't initialize the item later, in
which case it is the same). But note that both snippets are not
equivalent. The first case does not check that the id is a valid id. If
it is not, you will get an error when flushing (because of the DB
constraint).
So the first case is not usable when the id comes from an untrusted
source (user input for instance)
