I want to get a video file from another server, and open it on my website in flowplayer.
I did this :
$ch = curl_init('http://example.com/file.flv');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
header("Content-Type: video/flv");
header("Content-Disposition: attachment; filename=video.flv;" );
header("Content-Length: ".$size);
readfile($result);
But there is a problem with the size of file, it always shows wrong size of file (too small)
I have to use a cURL, because only my server IP can get a video from video server.
Thanks for help
readfile() is used to reads a file and write it to the output, use echo instead of, otherwise, use strlen to get content length, try the code below:
$ch = curl_init('http://example.com/file.flv');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$size = strlen($result);
header("Content-Type: video/flv");
header("Content-Disposition: attachment; filename=video.flv;" );
header("Content-Length: ".$size);
echo $result;

In my project, I need to download a file, and I need to use PHP.
All the results from Google were eventually not very helpful.
After combining code from 2 results, I ended up attempting:
function downloadFile($url, $filename) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$data = curl_exec($ch);
curl_close($ch);
header('Content-Description: File Transfer');
header('Content-Type: audio/*');
header("Content-Disposition: attachment; filename=\"$filename\"");
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($data));
readfile($data);
}
The result is an audio file, weighs 10KB (should be 3.58MB).
This code isn't the same as the code in the question that was suggested as a duplicate - here there's a section of curl functions and headers, while the question's answer only has a bunch of headers.
When opened the file with VLC - the following error appears:
Also, I tried using:
file_put_contents($filename, file_get_contents($url));
This one results in downloading the file to the path in which the PHP file is located at - which is not what I want - I need the file to be downloaded to the Downloads folder.
So now I'm basically lost.
What's the appropriate way to download files?
Thanks!
I successfully did it, thanks to Google and a lot of experiments.
The final code:
function downloadFile($url, $filename) {
$cURL = curl_init($url);
curl_setopt_array($cURL, [
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_FILE => fopen("Downloads/$filename", "w+"),
CURLOPT_USERAGENT => $_SERVER["HTTP_USER_AGENT"]
]);
$data = curl_exec($cURL);
curl_close($cURL);
header("Content-Disposition: attachment; filename=\"$filename\"");
echo $data;
}
I made a script where depending on the request the server will return a specific file for download from an external source, I use an external source because I have unlimited bandwidth on the other server:
$ch = curl_init();
$url="http://www.example.com/downloads/$fileName";
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true); // make it a HEAD request
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$head = curl_exec($ch);
$mimeType = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);
$size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Type: $mimeType");
header("Content-length: $size");
header("Content-Transfer-Encoding: binary");
header("Content-Disposition:attachment;filename='$fileName'");
readfile($url);
$filename comes from the request on the front end. It is a simple post from a form.
Everything works great, but some users, not all, have reported that they cant open the file because the file name has quotes: 'filename.zip', instead of filename.zip
I hit a wall, I have no idea even where to start looking, apparently this happens with some mac users. Any ideas?
The HTTP standard would have you putting double quotes around the filename parameter in the Content-Disposition header. That might look like this in your code:
header('Cache-Control: public');
header('Content-Description: File Transfer');
header('Content-Type: ' . $mimeType);
header('Content-Type:application/octet-stream');
header('Content-length: ' . $size);
header('Content-Transfer-Encoding: binary');
header('Content-Disposition:attachment;filename="' . $fileName . '"');
readfile($url);
Note here that I have changed all your PHP string definitions to use single quotes to present all string definitions consistently.
We are hosting some heavy files that are advertised as free downloads on one of our sites. These files are on another server so in order to generate the download we execute this code:
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Type:application/octet-stream");
header("Content-Transfer-Encoding: binary");
header("Content-Disposition:attachment;filename='$fileName'");
readfile("http://mysiste.com/downloads/$fileName");
Where $fileName is the name of the zip files. Example: myfile.zip
All works fine except that if myfile.zip is 8Mb on the server it will download as 16Mb! The craziest thing is that the file works fine and when unzipping the file all the files inside are complete and not corrupted.
I guess it has something to do with the headers and the transfer encoding as if the zip file looses the compression.
Any ideas?
I think you are missing out an important header
header("Content-length: $size") here. You can use int filesize (string $filename) to find the file size. Here is the API doc
<?php
$fileName = "downloaded.pdf"
$size = filesize($file);
header('Content-type: application/pdf');
header("Content-length: $size");
header("Content-Disposition: attachment; filename='$fileName'");
readfile($file);
?>
If the file is located in a remote server, you can GET the Content-length easily by setting up the Curl without actually downloading it.
These stackoverflow threads should help you:
Easiest way to grab filesize of remote file in PHP?
PHP: Remote file size without downloading file
Reference credit: Content-length and other HTTP headers?
This is the code that would combine curl and PHP headers:
$url="http://mysite/downloads/$fileName";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true); // make it a HEAD request
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$head = curl_exec($ch);
$mimeType = curl_getinfo($ch, CURLINFO_CONTENT_TYPE);
$size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
$path = parse_url($url, PHP_URL_PATH);
$filename = substr($url, strrpos($path, '/') + 1);
curl_close($ch);
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Type:$mimeType");
header("Content-Disposition:attachment;filename='$fileName'");
header('Content-Length: '.$size);
readfile($url);
I hope this helps!
I've face weird problem below url when I copy and paste it into download manager, it works fine. But I am going to stream it in direct link via PHP then get an 400 error. However when I use the link into different upload center site (uploadboy.com) to test if the link works fine or not, it was working fine on the uploader.
I coded a script that I attach to affix. And try many different way to download it but still face error 400!
What action do I have taken to fix the problem?
I test to see if the script works urlencode and urldecode function on whole parts of url and on query string of url. in these 4 different ways no success to download. However I attached my script in one of the way I tested.
I notice you again. the link working fine and it's not limited to IP Address. However Download Manager that I test to download the url have same IP address with php webserver.
Sample of URL:
http://r5---sn-p5qlsnsk.googlevideo.com/videoplayback?ipbits=0&mm=31&fexp=9407724,9408142,9408592,9408705,9408710,9408982,9412517,9412776,9413317,9413355,945137,948124,952612,952637,952640,952642&id=o-ACIY_VMiJqYl9lskpYea7F_6tP6DNv6WlJattCarpNST&signature=0DF7579F401F8BB481A4511F96ECD95C52FB618B.29AA2A450464D709E3FC3974759459A1EB7066E9&nh=IgpwcjAzLmlhZDA3KgkxMjcuMC4wLjE&key=yt5&mt=1432113172&ip=198.50.235.216&upn=aR3Slhiml7g&expire=1432134981&sparams=dur,id,ip,ipbits,itag,mime,mm,ms,mv,nh,pl,source,upn,expire&mime=video/3gpp&sver=3&pl=23&source=youtube&mv=u&dur=87.817&itag=17&ms=au&signature= '&title='Youtube-API-V3-Drag--Drop-PlayList--Download-videos--Search-Keyword'
Sample of Code to stream:
$url = $_POST['url'];
$referrer = $_POST['referrer'];
if(strstr($url,'googlevideo.com')){
$url_parts = parse_url($url);
$query = $url_parts['query'];
$query_parts = parse_str($query,$queries);
foreach ($queries AS $key=>$value){
$post_url .= $key.'='.urlencode($value).'&';
}
$post_url = rtrim($post_url, '&');
$url2 = 'http://r1---sn-u2oxu-f5f6.googlevideo.com/videoplayback?'.$post_url;
die($url.'<br><br>'.$url2);
$filename = preg_replace('/[^a-zA-Z0-9-_\.]/','', $title).'.'.getExtension($mime);
// $head = array_change_key_case(get_headers($url, TRUE));
// $filesize = $head['content-length'];
header('Pragma: public'); // required
header('Expires: 0'); // no cache
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Cache-Control: private',false);
header('Content-Type: '.$mime);
header('Content-Disposition: attachment; filename="'.basename($filename).'"');
header('Content-Transfer-Encoding: binary');
// header('Content-Length: '.$filesize); // provide file size
header('Connection: close');
// echo getUrl($url,$_SERVER['HTTP_USER_AGENT'],$referrer);
$file = fopen(str_replace('&','&',$url), 'rb');
while (($content = fread($file, 20480)) !== false) { // Read in 2048-byte chunks
echo $content; // or output it somehow else.
flush(); // force output so far
}
fclose($file);
exit();
}
Update1:
I already test below curl function:
function getUrl($url,$agent='',$referrer='',$proxy=''){
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
if(!empty($agent)){
curl_setopt ($ch, CURLOPT_USERAGENT,$agent);
}
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
if(!empty($referrer)){
curl_setopt ($ch, CURLOPT_REFERER, $referrer);
}
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,false);
$output=curl_exec($ch);
curl_close($ch);
return $output;
}
The 400 error comes from a typo in your url: remove the space character in this part: &signature= '&title='.
Your curl function is ok, but it doesn't work with your url. I don't know why not, but it works with an url like this: https://youtu.be/LxBk5f6mr-A.
Perhaps you can use the tool mentioned in this post:
grabbing youtube video URL from curl or get_video_info
I had a code that worked, here:
if (isset($_GET['file']) && isset($_GET['name']))
{
$file = base64_decode($_REQUEST['file']);
$ch = curl_init($file);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
$data = curl_exec($ch);
curl_close($ch);
if (preg_match('/Content-Length: (\d+)/', $data, $matches))
{
// Contains file size in bytes
$contentLength = (int)$matches[1];
}
header("Content-type: application/x-file-to-save");
header("Content-Disposition: attachment; filename=".$_REQUEST['name']);
header('Content-Length: ' . $contentLength);
header('Content-Transfer-Encoding: binary');
#readfile($file);
}
And than I changed my server to a differenf host providor, and the code stoped working. When I download from chrome it just keeps loading and loading,
but when I download from a download manager like IDM than it gets the correct name and size, but when I press start it makes an error that says something about not supporting resuming or something...
Again, the code worked when I used a different providor.
It might be errors which are outputted before readfile() use ob_clean();
flush(); to remove any output before readfile
