For anyone struggling to force the download of PDFs, I've found this very helpful!
<?php

// WARNING:
// This script might compromise your server's security.
$fn= $_GET['fn'];
// as a security measure, only serve files located in our directory
if( $fn && $fn=== basename($fn) ) {
// make sure we're serving a PDF (and not some system file)
if( strtolower( strrchr( $fn, '.' ) )== '.pdf' ) {
if( ($num_bytes= @filesize( $fn )) ) {
// use file pointers instead of readfile()
// for better performance, esp. with large PDFs
if( ($fp= @fopen( $fn, 'rb' )) ) { // open binary read success
// try to conceal our content type
header('Content-Type: application/octet-stream');
// cue the client that this shouldn't be displayed inline
header('Content-Disposition: attachment; filename='.$fn);
// we don't support byte serving
header('Accept-Ranges: none');
header('Content-Length: '.$num_bytes);
fpassthru( $fp ); // this closes $fp
