Hi,
Can anyone point me to tutorials on how to change a filename for each
download? My goal is to give the downloader a random name for a picture or a
document, so he will never know what the original filename is.
Regards,
Summi

Try adding a Content-Disposition header:
header('Content-disposition: attachment; filename=fname.ext');
?>

I save the file using the temp filename given to it by PHP during the
upload process. If that's not possible, then some sort of hash (MD5 for
example) of the original file name would suffice. Then, when the user
requests that file, they have to request it with a URL like
file.php?file=hashname
The added benefit of this is that you can verify the user is logged in
or not too. The only problem would be if you were serving media files,
as no plugins I know of send all the correct headers for the media file
request, so your browser would see it as an anonymous request.
Thanks,
Ash

Hi,
I finally got the time to test your solutions, the following is the best
solution and causes a minimum stress on the server and a decent =
security.
header('Content-type: application/pdf');
header('Content-Disposition: attachment;
filename=3D"downloaded.pdf"');
readfile('original.pdf');
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the
past
(Script from php.net based on your hints.)
I have tested this in many ways, but before I did not know how this was
simple.

Try adding a Content-Disposition header:
header('Content-disposition: attachment; filename=3Dfname.ext');
?>
