how to I replace singleton classes using function scope static

What is the problem? What are you trying to replace it with?
Anything in particular? "Not using function scope" is not much
of a specification. Have you looked at possible implementations
of the Singleton pattern? Try googling it. Try looking in some
smart books (like the GoF one). Try looking in the archives.
This has been discussed so many times that it just doesn't need
to be repeated, honestly.
