Download file from non public html folder with php

Question

I have a number of files that are stored on the server, but not in the public_html directory. The idea is that users who are logged in can download the files, using $_SESSIO

You can use readfile to get output as the file in question. EG:

$file = '/absolute/path/to/file.ext';

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
    readfile($file);
    exit;
}
