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 want to create a download pdf file, but its always damaged
i had try this code in other function its working correctly but in this function the downloaded file is corrupt
source and downloaded file has same size its 3.899
this is my code before :
if (file_exists($dir)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($dir).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($dir));
readfile($dir);
exit;
}
and i had try this code too for this issue :
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . basename($file) . '"');
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . $length);
set_time_limit(0);
readfile($file);
exit;
i think the problem is in file size,
my code is work corretly in size under 1Mb but i dont know how to change max download size, i had try to search in php.ini but i cant find
====> update
i had try to change file to smaller size file (below 1Mb) but its still damaged
I have a code:
$name = "jeffrey.epub"; //for naming only
$file = "test/cover/cabang.epub"; //the real file to be downloaded
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="'.basename($name).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
but upon having the download file, it came out corrupted.i also change the header('Content-Type: application/octet-stream'); to header('Content-Type: application/epub+zip'); but still it was corrupted, i was wondering what is the problem that the file is being corrupted
I have a piece of code that works well on many servers.
It is used to download a file through the readfile php function.
But in one particular server it does not work for files bigger than 25mb.
Here is the code :
$sysfile = '/var/www/html/myfile';
if(file_exists($sysfile)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="mytitle"');
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($sysfile));
ob_clean();
flush();
readfile($sysfile);
exit();
When I try to download a file lower than 25mb there is no problem, when the file is bigger, the file downloaded is 0 bytes.
I've tried with the function read() and file_get_contents but the problem still present.
My php version is 5.5.3, memory limit is set to 80MB.
Error reporting is on but there is no error displayed even in log file.
Here is the complete solution thanks to the answer of witzawitz:
I needed to use ob_end_flush() and fread();
<?php
$sysfile = '/var/www/html/myfile';
if(file_exists($sysfile)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="mytitle"');
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($sysfile));
ob_clean();
ob_end_flush();
$handle = fopen($sysfile, "rb");
while (!feof($handle)) {
echo fread($handle, 1000);
}
}
?>
I've the same problem recently. I've experimented with different headers and other.
The solution that works for me.
header("Content-Disposition: attachment; filename=export.zip");
header("Content-Length: " . filesize($file));
ob_clean();
ob_end_flush();
readfile($file);
So try to change flush to ob_end_flush.
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);
