Download pdfs and not show in the browser

I have links in my web page that point to PDFs, that开发者_JS百科 are in my server. I don't want want pdfs to be viewed in the browser bur directly downlodable when a user click on the link

---

just set the right header info. PHP file should look something like this.

<? 
  header('Content-disposition: attachment; filename=huge_document.pdf');
  header('Content-type: application/pdf');
  readfile('huge_document.pdf');
?>

as depicted here
