File size is not visible in php download readfile

Question

I used below code to force browser start download:

//send file
$fileName = basename($fullPath);
$length = filesize($fullPath);

header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header('Content-length: ' .  $length);
header("Content-disposition: attachment; filename=$fileName");

readfile($fullPath);

exit;

Everything's ok except total file size is not showing in browser (Firefox & Chrome). I searched the community and also test below code in htaccess with no success :

SetEnv no-gzip dont-vary

SetEnvIfNoCase Request_URI ...

My web server is Apache and PHP is in version 8.3

Is there any other option to check?

Answer 1

Recently I had the same problem! Suggest that add this header too rather than htaccess solution

//to show file-size in browser
header("Content-Encoding: none");
