getcwd returns the working directory of the apache process. It has
nothing to do with modules.

A process may work in any directory. If, after it starts running, the
process performs a chdir(whatever_existing_dir) system call, all
subsequent calls to getcwd will return whatever_existing_dir. You can
see the working directory of a process with process ID x by running

ls -l /proc/x/cwd

Which path do you want to get? The path of the served file?


A: Because it reverses the logical flow of conversation.
Q: Why is top-posting frowned upon?
A: Top-posting.
Q: What is the most annoying thing in e-mail?

I'm sorry if I wasn't clear with my question! I want the path of the served
file and the problem is that it doesn't always returns the correct path,
sometimes it just returns "/".

In example, if the served file is, the path should be
/www/domain/a/b/c/abc/htdocs/index.html, but then without the index.html,
since the directory path is just /www/domain/a/b/c/abc/htdocs/. That is the
structure I have now, but in most cases it doesn't work. As I said before,
it looks like it works more often with forum software and blog software then
static content or non-complex php-scripts. I would really love to solve
this, so thank you for answering so far:)
