I have files of different extensions, So how can I define multiple extensions in one header. for example
header("Content-type: application/xml");
header("Content-type: application/txt");
Is there any possibilities are there, to define in a single header something like this
header("Content-type: application/xml txt");
Thanks in advance for your suggestions
If you want in downloading any type of file you can just use application/octet-stream.
header('Content-Type: application/octet-stream');
// for example this will download any type of 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);

code.php
$code = $_GET["code"];
$file = 'code/'.$code.'.html';
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');

Generated URL to download the file:

Well, I want to forcing download the html file, above code not working and it just preview the file at browser!
file_exists() returns false. Change your path with document root:
$code = $_GET["code"];
$file = $_SERVER['DOCUMENT_ROOT'] . '/code/' . $code . '.html'; // set your path from document root.
if (file_exists($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;
}
Try changing the content type to match the file type and setting the transfer encoding to binary:
header('Content-Transfer-Encoding: binary');
header('Content-Type: text/html');
Try this
$code = $_GET["code"];
$file = $_SERVER['DOCUMENT_ROOT'] . '/code/' . $code . '.html'; // set your path from document root.
if (file_exists($file)) {
header("Content-Type: text/html");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
unfortunately it was a encoding issue. I changed code.php encoding from UTF-8 to UTF-8 Without BOM then problem solved. Thanks for all answers and helps. I forgot that PHP header only works with UTF-8 Without BOM.
This is actually not possible.
The browser can always decide on its own, if the file should be downloaded or not.
The furthest you can go is sending the content-disposition header.
I'm trying to download an .msi file which it's actual size is 5.77 MB. When I execute the script the downloaded file will lose some bytes and will become 4.88 MB.
Code:
$file = 'apps/file.msi';
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 5');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
I tried even with the anchor tag and the same happend. I also changed the extension from .msi to .txt and the bytes were also removed from the downloaded file.
I just can't figure it out
try this
$file = 'apps/file.msi';
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"" . basename($file) . "\"");
readfile($file);
maybe your server is configured to gzip the content transferred

I see this tutorial to make download file but I have a problem
Here is my example
$file_url = "D:/my file name.doc"
header('Content-Type: text/json; charset=UTF-8;');
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . basename($file_url)."");
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($file_url));
ob_clean();
flush();
readfile($file_url);
Everything's well in ie or chrome. But when I using firefox to download file. The file download has my is the file name? How to fix that thanks
header('Content-Disposition: attachment; filename="' .basename($file_url).'"');
First of all you are missing ; on the end of the first line.
I think the problem is in filename with spaces.
Try to use readfile(urlencode($file_url)); instead of readfile($file_url);
You should quote filename.
header('Content-Disposition: attachment; filename="' . basename($file_url) . '"');
EDIT: It was as selected answer just with typo in it. Now I fixed it.
I need make xlsx file download from my site (but not from directly open file url like this: http://site.com/file.xlsx )
So, this is php code
$file = "somefile.xlsx";
header('Content-Description: File Transfer');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);
file is downloaded, his extension is .xlsx, but when trying open this file in ms excel, file not opened and I got error : excel cannot open the file.xlsx because the file format or file extension is not valid
Tell please, why this happened? where I am wrong?
After many years, I got same problem, and after searching, I got here again ))
This is solution, that worked for me:
$file = "somefile.xlsx";
// define file $mime type here
ob_end_clean(); // this is solution
header('Content-Description: File Transfer');
header('Content-Type: ' . $mime);
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"" . basename($file) . "\"");
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
readfile($file);
You must be using this code in middle of some other file.
The problem with headers is they need to be set first on a page. They will not work if you have even 1 single space echoing before them. So you need to ob_clean() [clean the buffer] before you are setting headers
Try
ob_clean();
flush();
$file = "somefile.xlsx";
header('Content-Description: File Transfer');
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
Remove:
ob_clean();
flush();
Add at the end of code:
exit();
The issue is that flush() will also throw in your *.xlsx file content some garbage it has in it and that will corupt your file, even if you use ob_clean();
For a better understanding go to php.net and read the difference between flush(), ob_flush() and find that you didn't even need them in the first case. Therefore you won't need the ob_clean() too.
This works for me:
header('Content-Description: File Transfer');
header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
header("Content-Disposition: attachment; filename=\"".basename($fileLocation)."\"");
header("Content-Transfer-Encoding: binary");
header("Expires: 0");
header("Pragma: public");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Content-Length: ' . filesize($fileLocation)); //Remove
ob_clean();
flush();
readfile($fileLocation);
I can download my microsoft word successfully if I named it in the filename by default. But if I use $variables to name it. The document extension will be unknown.
Sample:
$No = 1;
$Name = 'John';
$Test = 'Science';
//Download header
$document->save($doc);
header('Content-Description: File Transfer');
header('Content-Type: application/msword');
header("Content-Disposition: attachment; filename='$No_$Name_$Test.docx");
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($doc));
ob_clean();
flush();
readfile($doc);
So if i rename my filename as variables. The file download will be without the docx extension. Anyone can advise?
Thanks
Correct headers are
for Excel (*.xlsx):
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="' . $fileName . '"');
for Word (*.docx):
header('Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document');
header('Content-Disposition: attachment;filename="' . $fileName . '"');
Change this
header('Content-Type: application/msword');
to
header('Content-Type: application/octet-stream');
EDIT:
And change
header("Content-Disposition: attachment; filename='$No_$Name_$Test.docx");
to
header("Content-Disposition: attachment; filename=\"{$No}_{$Name}_{$Test}.docx\"");
The correct use of that header is:
Content-Disposition: attachment; filename="fname.ext" note that if the name contains spaces it must be quoted
