Thanks, that did the trick. I'd done a google search before but didn't come up with any answers but hadn't added headers to the search phrase. In case anyone is interested in the solution, my script included session_start and I found that by adding session_cache_limiter("none") before session_start resolved the problem (http://bytes.com/forum/thread554529.html) Robbert From: Tom Chubb [mailto:tomchubb@xxxxxxxxx] Sent: Wednesday, July 16, 2008 1:41 AM To: Robbert van Andel Cc: php-general@xxxxxxxxxxxxx Subject: Re: Downloading a file On 16/07/2008, Robbert van Andel <robbert@xxxxxxxxx> wrote: I am having trouble getting a file to download to work in Internet Explorer. The site works fine in FireFox. The page retrieves the contents of a file from a database and outputs the following <?PHP header("Content-type: application/octet-stream"); header("Content-Disposition: attachment; filename=\"{$data['filename']}\""); header("Content-Description: PHP Generated Data"); echo $data['file']; ?> Where $data['filename'] is the name of the file as stored in the database and $data['file'] is the contents of the file. The script used to download the file is called view.php. As I mentioned, this works great in FireFox but with Internet Explorer, I get the following error: Internet Explorer cannot download view.php from www.yourdomain.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. Any help would be greatly appreciated.
