Mladen,
But if you're going to use classes, you don't need to use private methods.
The problem he's trying to solve is namespace collision. He has two
different functions with the same name and occasionally he needs to
include both in a third file. In C this isn't a problem because you can
use static functions.
In PHP you don't need to use private methods - and may not want to use
them, since they can't be called from outside the class. Just having a
method as a member of the class is sufficient to resolve the namespace
collision. And it can still be called by non-members.
Of course, this really isn't different than having different function
names in the first place - which may still be the easiest way to go.
