Thanks for the welcome. Your script helped me solve a problem I was having with Firefox. It seems that Firefox doesn't like a simple <A HREF ...> to download an executable.
Anyway, both the php file and the file to download are located in the same directory for the time being to run some tests. If / is pointing to root (in my case htdocs, not public_html), then was it just downloading the first file it encountered? Shouldn't it give me an error that the file I was looking for was not found?
