inheritance problem

[Liquid Fire]

I am having a small problem.  I am building a framework and running into a inheritance problem.  I have a base class that is going to include common functions and a a few static instance of common object(url_helper, database, session, and logger)  Now the issue is that both url_helper and logger also extend from base which causes a creation loop.  My question is there a way to include an instance of a object inside the parent class of that object without creating that contact loop?  If that is not possible, I know i can just make those class not extend from base and just manually add the need classed that I am extended from base in directly into those classes.

I guess one way of fixing this issue is to create a separate class that create an instance of these classes and than have the base class get the instance from this class.  I am going to do this unless someone else thinks there is a better way of doing this.
