What are the ways to implement "php chain inheritance"?

Question

PHP

Let's say there is a Base class that implements __set __get and stores a single $registry property for storing data.
There are two more classes Controller and Entity
We need an inheritance scheme Base > Controller > Entity.
Just wondering, I'm not going to use such a crutch! Traits not to offer - I know.

Answer 1

class Controller extends Base 
{
...
}

class Entity extends Controller
{
...
}
