Filereference and require()

I have a file, lets call it genericfile.php, containing a require("a_specific_file"); Now, I want to use (thats include) genericfile.php in many of my other .php-files in the WHOLE directorytree. The problem is that "a_specific_file" can't be found trough genericfile.php if this is included someplace other in the directory tree. How can I tell php not to make defaultpath to the toplevel require() funcion call? -- Rasmus Resen Amossen | stud.mat.dat at the University of Copenhagen Jagtvej 120, -244 | http://www.math.ku.dk/muh 2200 Kbh.
