[PHP] Way for script to discover it's path?

[Ken Tozier]

I'm working on an auto-include mechanism for some complex scripts and  
rather than have all the paths to the various components hard coded,  
I'd like to have the script walk up the hierarchy looking for it's  
specified includes. Is it possible to do this? I looked at the  
various file related php functions but didn't see anything resembling  
'my_path()'

Thanks
Ken
