I would to know the command in a PHP script to get in output and save a file from my site.
Thanks
See here for a good description of how to force the output of a php script to be a download.
The basics of it are:
// Set headers
header("Cache-Control: public");
header("Content-Description: File Download");
header("Content-Disposition: attachment; filename=" + $filename);
header("Content-Type: application/zip"); // or whatever the mime-type is
// for the file you want to download
header("Content-Transfer-Encoding: binary");
// Read the file from disk
readfile($full_path_to_file);
As an addition (provided by Gordon's comment), see the 1st example on the php documentation here
At the End of the files or used in clicking files, you can add this
$filesh = "check.xls";
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=".basename($filesh));
header("Content-Description: File Transfer");
readfile($filesh);
if you got any header using problem means, top of the file you can add ob_start(); function
If you mean getting output, contents from other site or location, this what you need file_get_contents

binaryhere is my problem
I'm working with php, I create a zip archive thx to ZipArchive library.
I complete it with all files I need and save it on my server.
Then I want to make it download by the current user, here is what I wrote :
if (file_exists($zip_archive))
{
header("Pragma: no-cache");
header("Expires: 0");
header("Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/force-download");
header("Content-Disposition: attachment; filename=\"".$zip_archive."\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($zip_archive));
ob_end_flush();
readfile($zip_archive);
}
But when I download the zip archive, I can see files inside, but when I try to extract them, an error occurs telling me that the file might be corrupted.
So I tried to open the zip archive saved on the server, and NO error appears.
Have you got any idea to help me ?
Thanks for any help.
(I changed fichier to binary, but a problem persists : End of archive ...)
This line:
header("Content-Transfer-Encoding: fichier");
Should read:
header("Content-Transfer-Encoding: binary");
You can read more about this header at http://www.w3.org/Protocols/rfc1341/5_Content-Transfer-Encoding.html. There is also a list of available encoding types, suffice to say 'fichier' isn't there.
I am facing a problem of downloading script, whenever download on my project site starts, all links present in the site does not work at all.
Once file gets downloaded completely, link starts working.
I am setting header and using readfile method of php for download the file. I want that file downloading should work simultaneously with users actions on the site.
I am using following code
header("Pragma: public");
header("Expires: 0");
header("Content-Type: application/$ctype");
header("Content-Description: File Transfer");
header("Content-Disposition: inline; filename=$docName");
header('Content-Length: '. filesize($filename));
header("Accept Ranges: bytes");
header("Content-Transfer-Encoding: binary");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
readfile("$filename");
Here filename is name of file and ctype is file type.
How to resolve this?
Please let me know if anybody have solution for this.
I'm just guessing that you're missing a proper header, change content type and transfer encoding as you need
$download is the actual file i.e. /var/www/download_images/1.jpg
$filesize is the size of the file
$filename can be any filename that you want presented to the user i.e. homer_simpson.jpg
<?php
if (file_exists($download))
{
header("Cache-Control: must-revalidate");
header("Expires: 0");
header("Pragma: public");
header("Content-Description: File Transfer");
header("Content-Length: ". $filesize .";");
header("Content-Disposition: attachment; filename=" . $filename);
header("Content-Type: application/octet-stream; ");
header("Content-Transfer-Encoding: binary");
ob_clean();
flush();
readfile($download);
}
?>
<?php
$file = $_GET['name'];
$path = './curr/'.$file.'.pdf'; // the file made available for download via this PHP file
$mm_type="application/pdf"; // modify accordingly to the file type of $path, but in most cases no need to do so
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: " . $mm_type);
header("Content-Length: " .(string)(filesize($path)) );
header('Content-Disposition: attachment; filename="'.basename($path).'"');
header("Content-Transfer-Encoding: binary\n");
readfile($path); // outputs the content of the file
?>
This is a snippet of code in file.php. I am referring to the file using:
File 1
The intent is that on click of the link, ./curr/First File.pdf should download. I do get a download, but on inspecting, it's the webpage with the pdf embedded in the file. Could anyone assist?
If you want to have just the PDF loaded, the above code is all code to be executed.
Drop all surrounding menus, header or footers. Make sure, that no HTML or any other output besides the PDF from readfile() remains, when calling this link.
Try to change the content type to :
header("Content-Type: application/force-download");
I have the following code to push a zip file for download.
$filename = "ResourcePack_".time().".zip";
$destination = $basepath."downloads/$filename";
if($this->createdownload($files,$destination,false)){
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Length: ". filesize("$destination").";");
header("Content-Disposition: attachment; filename='$filename'");
header("Content-Type: application/octet-stream; ");
header("Content-Transfer-Encoding: binary");
ob_end_flush();
#readfile($destination);
if(file_exists($destination)){
unlink($destination);
}
}
I know the createdownload function is working to generate the zip file just fine because I see the file being created on the server. The problem is file is being written to the browser as a bunch of garbage instead of opening a download stream. Am I missing something in my headers?
EDIT
I was right. My problem is not with the php, but that calling the php file that generates this code via a JQuery $.ajax call is the problem. Using $.ajax automatically sets the Accept-Encoding request header to values incompatible with zip files. So, intead of using $.ajax I just used a simple window.open javascript command to call the same php page and it works just fine with the headers.
try to put a die after the #readfile
and remove the #, to see if you have any other error related with the file reading.
i have some code doing the same thing and this works for me:
header("Pragma: public");
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-Disposition: inline; filename="' . $filename . '"');
header('Content-type: application/zip');
//header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($destination));
readfile($destination);
die();
try passing proper type for that file. I think its fileinfo mime type see http://www.php.net/manual/en/ref.fileinfo.php
header("Content-Type: $file_type");
Also you have semicolon after octet-stream remove it
header("Content-type: application/octet-stream");
I have a php-download script that looks like this:
<?php
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=\"$file\"");
header("Content-Type: $mimeType");
header("Content-Transfer-Encoding: binary");
header("Content-Length: $size");
// Read the file from disk
readfile($path);
?>
Normally with this I can force my E-Book-Reader (a Sony PRS-T1) to download a file. However, if I use the same script inside of a folder with .htaccess-authentication, the download fails.
On my computer, the download works, no matter if there is a .htaccess-authentication or not.
Can you help me to find the reason for this behaviour of my Ebook-Reader and make downloads inside of protected folders possible?
Thank you!
[edit]
The PRS-T1 runs Android. Maybe this issue (link) is the answer - it is simply not possible...?
