This is the function to provide "force download" headers which I've been
using for years now. I haven't tested it with IE8 yet...

/**
 * Sends out the necessary headers to force a download in various browsers
 *
 * @param	string	file name for download client
 * @param	string	mimetype
 * @return -
 */
protected function DLHeader ($disp_filename, $filetype) {

  // handle disposition
  $disp_attach = true;
  $disp_attach_txt="attachment";
  $disp_filename=ereg_replace('[^-a-zA-Z0-9\.]','_',$disp_filename);
  $cont_filename=$disp_filename;

  // figure out internet explorer version for quirks below
  $isIE=((preg_match('/compatible;
MSIE(\d*)/',$_SERVER['HTTP_USER_AGENT'],$matches)) &&
(strpos($_SERVER['HTTP_USER_AGENT'],'Opera')===false));
  $isIE6=(($isIE) && ($matches[1]>5));

  // filename should be quoted unless we're attaching on pre-IE6
  if ((!$disp_attach) || (($disp_attach) && ((!$isIE) || ($isIE6))))
$disp_filename="\"".$disp_filename."\"";

  // determine content-type
  // modify this for serving local files
  if (!$disp_attach)  $cont_type=$filetype;
  elseif (($isIE) && (!$isIE6)) $cont_type="application/download";
  else    $cont_type="application/octet-stream";

  // set headers

  // Output the headers for last-modified en content-length;
  // We extract these from the http headers we harvested from a check on
the fileserver
  // modify this for serving local files
  header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
  header("Content-Disposition: ".$disp_attach_txt.";
filename=".$disp_filename.";");
  header("Content-Type: ".$cont_type."; name=\"".$cont_filename."\";");

  return(true);
}
