PHP - Block Downloading Pdf File

I have searched for the solution for so long and I still could not solve my problem. I have a localhost server where it stored some pdf files for download.  I implemented the following function to force the download:

if(isset($_POST['dlPDF']))
{

$file = $_SERVER['DOCUMENT_ROOT'] .'/Upload/'.$pdfName;

header("Content-Type: application/pdf");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$pdfName");
header("Content-Transfer-Encoding: binary");

// read the file from disk
readfile($file);
}

However I could not open the pdf file properly since it says "the pdf file is not correctly encoded". FYI, the downloaded pdf file is always a few Kb larger than the original file. Please kindly let me know if there is anything I can do to make the pdf readable and I appreciate your help.

I am trying to download a video file which has a wmv. The protocol is either mms:// or http://

I can see the video in my browser but I cannot download it using curl or wget in a program and I need to download a few of these.
They are publicly viewable so they are not private stuff.
The URL is http://210.150.12.140/vod11/tepco/other/1111_01.wmv?MSWMExt=.asf
or
mms://wmt.stream.co.jp/vod11/tepco/other/1111_01.wmv

All I get at the moment is a text file of less than 1K and not the movie itself.
How would I download this file please?
Thanks
Paul

Hello There  ,

header("Content-type: image/jpg");
header("Content-Disposition: attachment; filename=test.jpg");

how can i direct to a specified path to select a certain file then download it .

example
let's say i have a folder that contains 2 files:
download.php and image.jpg

how can i download the image.jpg from the server with the Save As window??

Hello everyone.
I have a problem with some of my php script.

I have some php code that downloads a remote file and directly outputs it to the user. It works and all, it's just that when I do it on my Ubuntu LAMP server, downloading a file takes up a lot of ram. On my Windows WAMP server it works correctly and doesn't use up so much ram. Is this a problem with my code, or is it a server configuration?

Below is the code I use to download the file.
Code: [Select]

public function output_file($file, $name, $mime_type='', $size)
   {
   session_write_close();
    /*
    This function takes a path to a file to output ($file),
    the filename that the browser will see ($name) and
    the MIME type of the file ($mime_type, optional).
   
    If you want to do something on download abort/finish,
    register_shutdown_function('function_name');
    */
    if(is_readable($file)) die('File not found or inaccessible!');

    $size = $size;
    $name = rawurldecode($name); */
