Extending classes

[miarde]

I have a stupid question:

What's the best way to have numerous objects share the same instance of another object?

• Store the instance in the session?
• Have a "registry" singleton that contains each instance
• Use the $_GLOBALS array ( there I said it).

There will be quite a few sharable objects so I don't want to go passing references to the constructors of each class.

Your thoughts are appreciated.

If there should only ever be one instance of that other object, a singleton would be appropriate.
