I think his point is that if a certain model is referenced multiple times in the same controller action, it should be singleton (i.e. a reference should be passed back by findByPk() instead of a copy with potentially stale data from the db.
I agree that would be great, but I don’t think you should hold your breath until this is implemented
Exactly, i really need it and it’s implemented in most modern frameworks. It’s described as a “must have” in the book “PHP objects, design patterns and practice”.
