If you, like most people, move a file it is not only that single file. 
It is a whole directory tree.  Using $_SERVER['DOCUMENT_ROOT'] would 
then break the code whereas dirname(__FILE__) would not.  I don't know 
about you, but I don't just wake up one morning and say "gee, I think 
I'll move that file".  If I move anything, it is an entire directory 
tree.  If I have to move just a single file, I do a grep for that 
filename and I also look inside that file for dependencies.  How about you?
