<?php
/* filename set at some earlier point by mechanism of your choice */
header("Content-type: application/unknown");
header("Content-Disposition: inline; filename=".$filename);
/* Now open the real file you want and write it out in raw (binary) form 
as if you were echoing or printing an html page. */
?>

The content type application/unknown forces a download instead of the 
browser attempting to render it (as would be done with jpegs, text, 
html, etc).  It's also possible to use application/octet-stream, but 
that's not dependable when the content is a jpeg or gif.  Once you've 
started with those lines, you can read in whatever file you're 
downloading and write it out as if it were going to the screen.  I use 
this all the time at work for creating downloadable tab separated value 
dumps of SQL queries.
