The idea is to allow an application to be distributed easily without any reconfiguration. If it doesn't need any variables to tell it where it is in the directory structure, it won't matter where it is placed in someone else's application-- it will just work because of the relative includes.
Furthermore, while this is a very specific example, I am interested in the more general question of scoping in PHP. It seems to me that it would make more sense to have to declare a variable as "local" instead of having to declare it as "global." THe problem with a "global" declaration is especially important within a class: it does not make the variable global to the object, but instead global to the entire request. There is no way to get at that middle ground. I'm afraid I am not articulating myself very well... Do you get what I am after?
