[SOLVED] Downloading with PHP

[PutterPlace]

I am trying to figure out a way to remotely download files using PHP (and cURL if needed). For example:

 

Remote File to Download: http://www.domain2.com/file.jpg

 

Script To Download The File: http://www.domain1.com/download.php?file=http%3A%2F%2Fwww.domain2.com%2Ffile.jpg

 

 

I want this script to be able to force the user to download the file instead of opening the file in the browser. Any help would be greatly appreciated.

All that will do is basically redirect the user to where the download will be. Are you trying to hide the download url?

Yea I would like to hide the download URL. I was hoping to use cURL so that it appears all traffic is coming my own site.

Simple solution:

 

download.php

<?php
if (!$_GET) {echo 'No download id set.'; exit;}
//URLs can't contain spaces
$allowed = array('http://www.phpfreaks.com/images/logo_main.jpg', 'http://download.microsoft.com/download/a/8/7/a87b3d05-cd04-4743-a23b-b16645e075ac/readme.txt');
$id = $_GET['id'];
$url = $allowed[$id];
$filename = basename($url);
header('Content-type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$filename.'"');
echo file_get_contents($url);
exit();
?>

 

download.php?id=0 will now prompt the user to download the first file in the $allowed array.

 

The script works in recent Firefox and IE versions; not sure about older browsers. Look up some other force download scripts if you want better compatibility (i.e. find out which other headers to send). But remember that file_get_contents() probably will time out on large files.

or you can try:

 

<?php

$saveName = stripslashes($_GET["name"]);
$savePath = stripslashes($_GET["path"]);

header("Content-Type: application/force-download"); 
header("Content-Disposition: attachment; filename=$saveName");
header("Content-Transfer-Encoding: binary");
header("Content-length: " . filesize($savePath));
readfile($savePath); 

?>

 

save that file as download.php

then just type

http://www.mywebsite.com/download.php?name=File.jpg&path=file.jpg

 

name = the name its going to be downloaded as

path = the url of the file

 

 

EDIT:

oh sorry,

I didnt notice that you were trying to get the file off a

different server. This script only works for downloading

off of your server.

But that wont hide the path of the actual files. I've added a bit of error checking to my script above:

 

<?php
if (!$_GET['id']) {echo 'No download id set.'; exit;}
//URLs can't contain spaces
$allowed = array('http://www.phpfreaks.com/images/logo_main.jpg', 'http://download.microsoft.com/download/a/8/7/a87b3d05-cd04-4743-a23b-b16645e075ac/readme.txt');
$id = $_GET['id'];
if (!ctype_digit($id) || $id >= count($allowed)) {echo 'Wrong download id.'; exit;}
$url = $allowed[$id];
$filename = basename($url);
header('Content-type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.$filename.'"');
echo file_get_contents($url);
exit();
?>
