Static classes inheriting from abstract class in PHP

I have stumbled upon an interesting problem/bug that I eventually solved, but the solution is not what I expected or would like it to be.

The setup is simple. There is an abstract static class Factory, which has a reference to a singleton (Registry) as well as two static properties, model and table.

There are a number of static classes building upon/inheriting from this abstract class and they all have an init() method in which they set the model and table properties. Of course, since model and table are开发者_如何学Go static they can only have one value which is the same for all the child classes of the abstract Factory class. This is the problem/bug.

However, my aim is to have each child class have its own model and table so I am forced to declare model and table in each child class as a static property. This seems a bit cumbersome (and not very DRY), but it seems to me that this is the only solution if I want to have (1) the classes inherit from the abstract Factory class and (2) remain static.

Is my assumption correct or is there another approach that I am missing?

---

The goal is to have different values for $model and $table in different static child classes?

Assuming that is the case, I don't see how You could possibly accomplish that without explicitly defining them different in each child class.

I don't think it is cumbersome. I see it as a good practice - by keeping functionality where it belongs.
