For IE I'd force this content-type:

    header('Content-Type: application/octet-stream');
    header("Content-Length: $filesize");
    header('Content-Disposition: attachment; filename="' . $filename . '"');
    header('Content-Transfer-Encoding: binary');
    fpassthru($fp);
    fclose($fp);
    exit;

I'd recommend fpassthru as well, especially for large / popular files.

For common file types (jpg, gif, zip, etc) I'll use that Content-Type
explicitly, but IE and PDFs have given me enough grief in the past to
have to resort to the infamous 'octet-stream'.

Cheers,

Rich
