I am trying to download 700mb file using the following code
header("Pragma: public", true);
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=".basename($File));
header("Content-Type: application/download");
header("Content-Description: File Transfer");
header("Content-Length: " . filesize('movies/'.$File));
flush();
$fp = fopen('movies/'.$File, "r");
while (!feof($fp))
{
echo fread($fp, 65536);
flush();
}
fclose($fp);
but this is taking too long to start downloading file, it takes about 2-3 minutes to start the download. This code is just for mkv file, other video files are working perfect with location header.
File is not downloading without any of the content-type header missing
I want to start downloading fast

i have a code like this :
header("Pragma: public", true);
header("Expires: 0"); // set expiration time
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Content-type: application/rar');
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header('Content-Type: application/download');
header('Content-Disposition: attachment; filename='.$fullname);
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($fullname));
$fp = fopen($fullname, "r");
fpassthru($fp);
fclose($fp);
based on above code, download is running, but the tar.gz cannot be opened.
how to solve it? is it possible to download tar.gz?
Content type for GNU zipped archive is application/x-gzip.
You should use below code to set content type
header('Content-type: application/x-gzip');
I'm trying to get a link to download files without redirecting, or using another file to download large zip files.
It works great for files under ~100mb, but anything larger and it's sent to an error page in chrome that says: Error code: ERR_INVALID_RESPONSE.
The $file and $path are put into a form with jQuery, and then $('form').submit(); is called.
function downloadFile($file, $path){
set_time_limit(0);
$fullPath = $path . $file;
if ($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 'attachment' to force a download
break;
default;
header("Content-type: application/octet-stream");
header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
}
header("Content-length: $fsize");
header("Cache-control: private"); //use this to open files directly
while(!feof($fd)) {
$buffer = fread($fd, 2048);
echo $buffer;
}
}
fclose ($fd);
exit;
}
Any ideas why it fails on larger files?
Update:
When I use the following code, it downloads the file, but the finished file doesn't open as it's corrupted for some reason:
set_time_limit(0);
ini_set('memory_limit', '1024M');
// http headers for downloads
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$filename."\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".$file_size);
ob_end_flush();
#readfile($fileinfo['path']);
When I use this code, it only downloads the first 49.7kb then says it's finished, I even tried ob_flush() and flush() together:
// http headers for downloads
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$filename."\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($fileinfo['path']));
if ($fd = fopen ($fileinfo['path'], "r")) {
set_time_limit(0);
ini_set('memory_limit', '1024M');
while(!feof($fd)) {
echo fread($fd, 4096);
flush();
}
}
The only thing I do different in my downloader is Content-Transfer-Encoding: chunked. Also take the flush() out of the loop and make sure you do ob_clean(); flush(); before and ob_end_flush(); after sending the data.
I have the following code in an attempt to have it so a specific file on the server is downloaded:
$file = 'upload/Order.txt';
header("Pragma: public", true);
header("Expires: 0"); // set expiration time
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment; filename="basename.$file);
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
All that happens is it causes the browser to download a file, in my case "Order.txt", but its blank, it is just creating this file out of no where. It doesn't do anything with the "upload/" path portion of $file.
Thanks for any help, I find headers really confusing, why I can't just have "download ($file)" is beyond me.
Edit: I'll struggle over a problem for days, finally decide to ask here then immediately after fix it my self.
I changed the location of the file to be in the same as the PHP script, I'd still like to know how to make it work with them being separate however. I also added:
readfile($file);
If I alter with of these 2 changes it doesn't work.
Also slim lined it, new code:
$file = 'Order.txt';
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=$file");
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");
readfile($file);
you should print content of file to stdout after headers:
$file = 'upload/Order.txt';
header("Pragma: public", true);
header("Expires: 0"); // set expiration time
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Disposition: attachment; filename=".basename($file));
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($file));
$handle = fopen($file, "r");
$contents = fread($handle, filesize($file));
fclose($handle);
echo $contents;
Try change this line:
header("Content-Disposition: attachment; filename='".basename($file)."';");
I'm having lot of issues with Safari. When I provide a download from a PHP script the downloaded file has ".html" extension appended. Despite the HTTP headers I send to the client, I found them changed in inspector; in particular the mime-type is always set to text/html.
Here what I'm sending to the browser:
<?php
....
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: public, must-revalidate, post-check=0, pre-check=0");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=\"{$file['name']}\"");
header("Content-Type: ".$file['type']?$file['type']:'application/octet-stream');
header("Content-Transfer-Encoding: binary");
header('Content-Length: ' . filesize($file['file']));
ob_end_flush();
#readfile($file['file']);
Where $file contains:
$file = array(
'name'=>'myfile.zip',
'file'=>'/tmp/myfile.zip',
'type'=>'application/zip'
);
What can I do?
I'm trying to download a CSV file through the browser. The script is partially working, because so far I managed to display the CSV on screen, but the download is not starting.
Here is what i tried so far:
if(isset($currency)) {
header("Content-Type: application/csv");
header("Content-Disposition: attachment;Filename=Pricelogs.csv");
ob_clean();
$filename = "/tmp/".uniqid().".csv";
exportCSVFile($filename, $currency, $country, $provider);
readfile($filename);
//unlink("'".$filename."'");
} else {
echo "ERR_USERNAME_PASSWORD";
exit();
}
I had already read all questions of this type from FAQ & also tried but it gets open on browser only,instead of downloading.
I had also used header with single quotes.
I also tried header("Content-Type: text/csv");
Also:
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=\"".$filename."\";" );
header("Content-Transfer-Encoding: binary");
PUT your CSV file URL, it will display in browser in place of force browser to download. You can open it in iframe in your site.
http://docs.google.com/viewer?embedded=true&url=www.yoursite.com/filename.csv
I usually just do:
header('Content-type: text/csv');
header("Content-Disposition: attachment; filename=my_csv_filename.csv");
// print CSV lines here
exit();
I can tell you this combination is working for me:
$bom = chr(0xEF) . chr(0xBB) . chr(0xBF);
header("Content-type: application/csv; charset=UTF-8");
header("Content-Disposition: attachment; filename=$filename.csv");
header("Pragma: no-cache");
header("Expires: 0");
print $bom . $data;
exit;
If I were you, I would first test this plainly (outside of all your buffering), first see that you manage to make this work, and only then test it in your specific set up.
You might try this.
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename.csv\";" );
print $content;
For large files you need to get your output buffer started
add : ob_start(); at the start
ob_clean(); at the end of you file
