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.

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

Also easy. Set the Content-Type header to the file's corresponding MIME
