File Download Script Problem

[tshrinivasan]

Friends.

I am doing a file manager application.
I did the upload part.

now doing the download script.

<?php

$path = $_SERVER['DOCUMENT_ROOT']."/path2file/"; // play with the path if the document root does noet exist

$fullPath = $path.$_GET['download_file'];

if ($fd = fopen ($fullPath, "r")) {
$fsize = filesize($fullPath);
$path_parts = pathinfo($fullPath);
$ext = strtolower($path_parts["extension"]);
switch ($ext) {
case "pdf":
header("Content-type: application/pdf"); // add here more headers for diff. extensions
header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachement' to force a download
break;
default;
header("Content-type: application/octet-stream");
header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
}
header("Content-length: $fsize");
header("Cache-control: private"); //use this to open files directly
while(!feof($fd)) {
$buffer = fread($fd, 2048);
echo $buffer;
}
}
fclose ($fd);
exit;
// example: place this kind of link into your document where the download is shown:
// <a href="download.php?download_file=some_file.pdf">Do wnload here</a>
?>


I got from http://www.finalwebsites.com/snippets.php?id=4

The file downloads perfectly.
but, can not open any file.

For example, if the downloaded file is "sample.jpg", I can not open it with any image viewer or firefox.

but the file size is same as the original.

how to solve this problem?

thanks,
T.Shrinivasan.

If you check your headers, you have told the browser the file is a PDF.
Can you download and open a PDF?.
