download scrip

jeg har dette download script
men der er noget i vejen med for nu åbner det filen i stedet for at give muligheden for download. Hvad skal jeg skrive i header for at den tvinger download

  $path = $name;
  if (!is_file($path) or connection_status()!=0) return(FALSE);
#header("Cache-Control: no-store, must-revalidate");

  header("Cache-Control: post-check=0, pre-check=0", false);
  header("Pragma: no-cache");
  header("Expires: ".gmdate("D, d M Y H:i:s", mktime(date("H")+2, date("i"), date("s"), date("m"), date("d"), date("Y")))." GMT");
  header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");
  header("Content-Type: application/octet-stream");
  header("Content-Length: ".(string)(filesize($path)));
  header("Content-Disposition: inline; filename=\"" .$sangnavn. "\"");
  header("Content-Transfer-Encoding: binary\n");
  if ($file = fopen($path, 'rb')) {
  while(!feof($file) and (connection_status()==0)) {
    print(fread($file, 1024*8));
    flush();
  }
  fclose($file);
  }
  return((connection_status()==0) and !connection_aborted());
}
