No I wasn't intending to use ajax per-se. I was just using that as a

Is it necessary to call print or echo here?
OK, then we're on the same page here (no pun intended).
When running a PHP script that sets headers, the only requirement is
that you set the headers before _any_ content has been displayed.
Basically, that means that the very first characters of the PHP file
must be "<?php" and no echos or other content-generating commands are
run until after all headers are set. There's no requirement to call
echo, the headers are sent even if your page contains no content at
all.
I would print a directory listing of a directory containing
downloadable
files
to the browser with php, where each file listing is wrapped in an
anchor
that has the href value set to a script with a query attached:
something
along the lines of <a href="downloader.php?file=[file to
download]">[file
to download]</a>
Perfectly doable. Downloader.php simply needs to set the headers,
interpret the GET variable, and stream the file.
Listing the directory
is a separate problem, and you'll surely find plenty of tutorials by
searching online.
This I already have in hand. I am working currently on a CMS system
that uses a file browser application I wrote so I can designate a dir
to send
and upload file to, to select a path for a new file or rename a file,
a number
of related uses. It will list a single directory or all the
directories at and below
it. Now I can add a method to download files. I also have a web base
file editor
for plain text files that has open, save, and save as. So the file
browser works
vaguely similar to an open, save and save as file navigator in the Mac
and other
systems, but is web site based and applies to the web site content and
file structure.
I am thinking of any file type: .pdf, .rtf, .swf, .doc, mpg, mpeg,
mp3,
binary, as well as plain text, whatever
Also easy. Set the Content-Type header to the file's corresponding
MIME
type.
