?>
and i run the script on my computer which xampp is installed, and its absolutely works.
but i running it on my another computer, not working.

Heres a very crude way you can proxy the image and prompt a download.
<?php
$url = "http://www.branded3.com/wp-content/uploads/2011/05/Google_Chrome1.jpg";
//Get file
$source = file_get_contents($url);
//Image Mime types
$images = array('jpg'=>'image/jpg','png'=>'image/png','png'=>'image/png');
//Is it an image extention
if(in_array(substr($url,-3),$images)){
$type = $images[substr($url,-3)];
}else{
//No its somthing else
$type = 'application/octet-stream';
}
//Set the headers
header('Content-Description: File Transfer');
header('Content-Type: '.$type);
header('Content-Disposition: attachment; filename='.basename($url));
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . sprintf("%u", strlen($source)));
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Expires: 0');
header('Pragma: public');
//echo the source
echo $source;
?>

I can't download files that already uploaded in my website, for example :
I already uploaded a video file with 800mb file size and it is okay, the file is save to my directory in the File folder, then I want to download that file again, but as soon as I download the file, I will always got 1kb file not the exact size of the file, and when I play it, nothing happen
this is my code:
<?php
include 'db.php';
if(isset($_REQUEST['name']))
{
$var =$_REQUEST['name'];
$dir = "../files/";
$file = $dir . $var;
if(file_exists($file))
{
header('Content-Description: File Transfer');
header('Content-Type: video');
header('Content-Disposition: attachment;
filename='.basename($file));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
mysqli_close($conn);
exit();
}
else{
echo "File not found";
}
}
?>
Yeah, I had the same problem too. After searching alot on the internet, I found out that the problem is related to output buffering. The following code solved my problem.
<?php
$file = $_GET['file'];
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_end_clean(); //adding this line solves my problem
readfile($file);
exit;
?>
The code ob_end_clean() basically runs grabs everything in the buffer, then erases the buffer, and turns off output buffering.
I'm trying to download this file from DropBox, i tried the same code with a file on the same website that running the PHP script and it did work but now when i add a full ULR, it doesn't.
The problem is that the QR-Kodite.rar file is created in my Windows downloads folder but its size is 0 and Chrome says that the download has finished.
This is my code :
if(isset($_GET['App'])){
if(basename($_GET['App']) == $_GET['App']){
$path = 'https://dl.dropboxusercontent.com/s/pdg8bnpmbgvcsmd/QR-Kodite.rar';
$size = filesize($path);
header('Content-Type: application/octet-stream');
header('Content-Length: ' . $size);
header('Content-Disposition: attachment; filename=' . $path);
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
ob_clean();
$file = # fopen($path, 'rb');
if($file){
fpassthru($file);
$_SESSION["ITA"] = "No";
exit();
}
}
}
I'm trying to download pdf/jpg/jpeg/png using PHP. Here is my code
$result= mysqli_query("SELECT * FROM upload WHERE upload_id='$id'");
$row = mysqli_fetch_array($result);
//get file extension
$filename = $row['upload_name'];
$ext = pathinfo($filename, PATHINFO_EXTENSION);
if($ext=='jpg'||$ext=='jpeg'||$ext=='png' ||$ext=='pdf'){
echo "Download";
}
download.php
$name= $_GET['id'];
header('Content-Description: File Transfer');
header('Content-Type: application/force-download');
header("Content-Disposition: attachment; filename=\"" . basename($name) . "\";");
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($name));
ob_clean();
flush();
readfile("uploads/".$name); //showing the path to the server where the file is to be download
exit;
When I tried the above code, it can be download however, when I tried opening the pdf/jpg/png it says invalid. Is there anything wrong with my code? This is my first time using the download code. So I really dont know what is the problem.
And for this path as stated in the code below,
readfile("uploads/".$name);
How do I write it if my pdf/jpg/png files are saved here in my computer C:\Apache2.2\htdocs\epals\uploads
Please help thanks
I have scripted a download file on PHP. I use fpassthru but I cannot download any file. It just print binary code on my page. When I tried uploading it on host and it works fine.
Can anyone explain why my PHP file is not working on local?
Note: I am using XAMPP on Mac.
Here is my code:
$filename = $data['PathFile'];
$directory = '../upload/'.$filename;
if (file_exists($directory) && is_readable($directory)) {
$size = filesize($directory);
header('Content-Type: application/octet-stream');
header('Content-Length: '.$size);
header('Content-Disposition: attachment; filename='.$filename);
header('Content-Transfer-Encoding: binary');
$file = # fopen($directory, 'rb');
if ($file) {
fpassthru($file);exit;
}
Please Check your Directory or path. Giving an example of another code for download please try this.
$file = 'Pareshaan.mp4';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
I have created a beginner program to forcefully download file from unix box to windows through browser, it is not throwing any error but shows nothing on browser just a blank page.
PHP version- 5.2.13
Apache-2.0
Unix Box- HP-UX 11.11 (old version latest is 11.31)
local PC- windows XP Prof.
Browser- IE 7, Mozilla.
Below is my code (this code resides on unix box):
<?php
ob_start();
$file = '/opt/hpws/apache/htdocs/barn/file2';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream;charset=utf-8');
header('Content-Disposition: attachment; filename=$file');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
?>
This line had quotation marks missing:
header('Content-Disposition: attachment; filename=$file');
and in trying to use that line of code, the browser would prompt to save the file as $file.
The line of code should read as:
header('Content-Disposition: attachment; filename="'.basename($file).'"');
The following (tested with a binary file) with file inside the same folder as executed code.
NOTE: You could use header("Content-Type: application/text"); if it's an ASCII file.
<?php
ob_start();
$file = 'file.zip';
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream;charset=utf-8');
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
?>
Okay, let's add some checks and debugging.
<?php
$file = '/opt/hpws/apache/htdocs/barn/file2';
if (!file_exists($file)) {
die("The file does not exist");
}
if (!is_file($file)) {
die("Not a file"); // Worry about symlinks later
}
if (!is_readable($file)) {
die("The file is not readable");
}
die("DEBUG: Okay, will send the file -- remove this line and retry");
$name = basename($file); // Or anything else
header('Content-Type: application/octet-stream');
header("Content-Disposition: attachment; filename=\"{$name}\"");
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit();
?>
If this does not work, it should at least tell you why. Also, on the first run, the one when it will still not download the file but only tell you that it will, check that the page does not contain anything else except that one line. Otherwise, you're setting yourself up for a fall; if not this once, as soon as you have to send a file larger than your output buffers, or too many files for your system memory.
