My client wants an affiliate system developed. I already have an affiliate
system that works, but I need to extend it a little.

My client want that the affiliate like should be something like:
www.domain.com/rosegarden where rosegarden is the affiliates choosen
affiliate tracking.

1.I have a script that creates the folder rosegarden and copy
index.php file into that folder that contains the tracking script and then
just redirect them back to www.domain.com <http://www.domain.com/
2.I can use ModRewrite or something like that. But I have never used
that before, and I am curious of how difficult it would be to create a
dynamic system for this.

When the affiliate signs up they can choose their subfolder and the system
will automatically create necessary files and copy them.

, 1 is pure evil, 2 is overkill. My suggestion would be multiviews. If
you're using Apache (I assume you are since mod_rewrite is an option),
enable multiviews on the vhost and then create a file called a.php in
the root of the site. Affiliates link to (as your example)
/a/rosegarden. In a.php, grab $_SERVER['REQUEST_URI'], remove the /a/
from the start of it, what's left is the affiliate identifier. Process
as you like.
