RE: [PHP] How to change a filename for download (e.g. jpeg, pdf etc.)

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="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:

<?php
    header('Content-disposition: attachment; filename=fname.ext');
?>
