PHP - Downloading Images

I wonder if some kind-hearted person can help me?
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

Hello,

I'm trying to use php to have a user upload a file and then, have my site create a link --- I'm ALMOST there.    My last hitch is in creating the link.  From the code below,
Code: [Select]
echo "this is the current filename: ". $supplemental_file;
  echo '<a href=../../supplemental_files/' . $supplemental_file . '">Supplementary Download</a>';

I get:

this is the current filename: Complaint.doc

But, when I hover over the link, I get:

http://localhost:8888/algebra_book/supplemental_files/Complaint.doc%22

Any thoughts on the extra %22 ??

Thanks so much....

Hi
I am creating an e-commerce website, where users who pay with their credit card are able to download pdf books.
how can I make a PDF file only accessible for those users (who pay and validate their credit card) and not for everyone ?

I want to know the main idea about securing these files.

Hello,

Ive got a script that downloads a file to my server. I want to be able to download a file from a site such as FileServe using my premium details. Ive tried http://username:password@fileserve.com/file.rar but that dosent work, It just downloads a tiny small 30kb file.

Is there a way i can set a cookie or somthing so my script has access to download file using my premium account?

Thanks in advance

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); */

I need to dwonload a remote file say http://abc.com/files/abc.zip.
Assuming that the file size > 100MB

Is there a way to download the file in parts/chunks say 10MB each ?

Hello, I am new and am having a hard time with PHP. 

Scenario:  There are PDF files on my website that I want users to register before downloading the files.  I do not want them to login but rather provide basic information such as name and email address.  Once the form is submitted, I am not sure if I should be using PHPSESSION to validate the user.  Also, I am not sure where to place the files: either in the webroot (/var/www/) or outside.

I am new to PHP so please forgive me if I use terminology incorrectly.

Thank you for reading my question.

Hi,

I'm trying to figure out the best way to determine if a user is currently downloading a file from my website.
The way my site works, is the user waits 30 seconds and views an ad. After the timer is up the download becomes available.
I heard that I could probably use a timestamp or something of the sort. I've read up on it but not sure how I could go about this.

I have this code and its downloading file nicely. But I want to show a progress bar while downloading file from external server. My existing code shows progress bar but its not effective (ex. if i try to download two media file, one video and another audio, and video size is larger than audio size the audio finishes first and the progress bar shows 100% also suddenly it drops to 50% as the video is still downloading ). I mean it actually shows two progress and I need one. If I could get average percentage value of two progress that would be better. Any suggestion regarding this will be greatly appreciated.
 

<?php
set_time_limit ( 0 );
function define_progress_callback($i) {
global $conn;

curl_setopt($conn[$i], CURLOPT_PROGRESSFUNCTION, function ($resource,$download_size, $downloaded, $upload_size, $uploaded)
{
    if($download_size > 0)
        $progress = round($downloaded / $download_size  * 100);
        echo '<script language="javascript">$(".loader").loader("setProgress", '.$progress.');</script>';
        echo str_pad("",1024," ");
        flush();
        usleep(20000);

});
}

$urls = array("http://example.com/file.mp3",
                "http:/example.com/file.mp4");
$save_to='./tmp/';
$conn = array();
$fp = array();
$mh = curl_multi_init();

    foreach ($urls as $i => $url) {
    $g = $save_to . basename($url);
    $conn[$i]=curl_init($url);
    $fp[$i]=fopen ($g, "wb");
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);    // No certificate
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
        curl_setopt ($conn[$i], CURLOPT_FILE, $fp[$i]);
    curl_setopt ($conn[$i], CURLOPT_HEADER ,0);
    curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,60);
    curl_setopt ($conn[$i], CURLOPT_MAXCONNECTS, 10);
    curl_setopt($conn[$i], CURLOPT_NOPROGRESS, false);
    define_progress_callback($i);
    curl_multi_add_handle ($mh,$conn[$i]);
    }

    do {
    $n=curl_multi_exec($mh,$active);
    }
    while ($active);
    foreach ($urls as $i => $url) {
    curl_multi_remove_handle($mh,$conn[$i]);
    curl_close($conn[$i]);
    fclose($fp[$i]);
    }
curl_multi_close($mh);

?>

no code tags meant auto-embedding of mp3

I'm a newbie to PHP but I want to amend a website I run for a musician friend of mine so that when people purchase his albums (sold as ZIP files) they don't see the link to the actual file, but PHP generates a randomly named copy, then downloads it for them and then deletes the copy when complete.  All works well except the download.  With the large files the download goes to about 1/2 way through and then just stalls until it aborts. 

Here's the code...

Code: [Select]
<?php
$path = "../_downloads/"; // change the path to fit your websites document structure
$fullPath = $path.$_GET['file'];

if ($fd = fopen ($fullPath, "r")) {
    $fsize = filesize($fullPath);
    $path_parts = pathinfo($fullPath);
    $ext = strtolower($path_parts["extension"]);
    switch ($ext) {
        case "zip":
        header("Content-type: application/zip"); // add here more headers for diff. extensions
        header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachment' to force a download
        break;
        default;
        header("Content-type: application/octet-stream");
        header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
    }
    header("Content-length: $fsize");
    header("Cache-control: private"); //use this to open files directly
    stream_set_timeout($fd, 600);
    while(!feof($fd)) {
        $buffer = fgets($fd,8192);
        echo $buffer;
    }
}
$info = stream_get_meta_data($fd);
fclose ($fd);

if ($info['timed_out']) {
    echo 'Connection timed out!';
} else {
    echo 'Done';
}
    
exit;
// example: place this kind of link into the document where the file download is offered:
// <a href="download.php?file=some_file.pdf">Download here</a>

?>

The link to run it is below...
www.godfreyb.com/_scripts/download.php?file=cd12_vg.zip

I've tried the @readfile(); function and this does the same thing, get to about 60.5 Mb and stalls.  I even tried passthru('cat ' . $fullPath); to send the file and that doesn't send anything at all.

The site is hosted by FastHosts on a Windows 2008 server with PHP5 installed.

Directly linking to the ZIP file results in a perfect download everytime.

Can anyone suggest a way to get this working?  It's driving me nuts!

Hello,   I want the user to get authenticated before file download starts   Here is my code:    <?php
if (!isset($_SERVER['PHP_AUTH_USER'])) {
    header('WWW-Authenticate: Basic realm="My Realm"');
    header('HTTP/1.0 401 Unauthorized');
    echo 'Your request is cancelled';
    exit;
} else {
    //check $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW']
    if (isset ($valid)) {
        //start download

        $path = './data/negative_seq_60.txt';
        $type = "text/plain";

        header("Expires: 0");
        header("Pragma: no-cache");
        header('Cache-Control: no-store, no-cache, must-revalidate');
        header('Cache-Control: pre-check=0, post-check=0, max-age=0');
        header("Content-Description: File Transfer");
        header("Content-Type: " . $type);
        header("Content-Length: " .(string)(filesize($path)) );
        header('Content-Disposition: attachment; filename="'.basename($path).'"');
        header("Content-Transfer-Encoding: binary\n");

        readfile($path); // outputs the content of the file

        exit();
    } else {
        //show error
    }
}
?>   But on clicking download link, I am getting the following error : " Undefined variable: valid at line no 9".   Please help.

Hi,

I want to download more than one file at a time. But now I can't download any of them that way. I want to solve it the way it is in gmail, i.e. I download either 1 file separately or if there are two or more, it is zipped.

Thanks in advanced,

T

I have dozens of tables that a client needs to download through the web. I can use PHP to convert the tables within the database to a CSV however I have to split the files into 10k result chunks otherwise the server gets overloaded with memory.

I already raised the memory limit within the script that is downloaded (ini_set('memory_limit', '512M') which is able to make this happen.

Downloading these files piece by piece is a really time consuming. Is there a memory safe and efficient way to combine all my tables as CSV's and into one zip them into one master download? PHPMyAdmin seems to do this smoothly, however, I need an online interface for the client to export the data directly...
