A simple script to force a file download with PHP
With this script, it will be possible to force the download of a file with PHP, it is code to be customised with the valorisation of the $path and $name variables. Its purpose is to set up (force) the direct download of a file without making the absolute address of the file public.
The values of path and name can be enhanced by a reading from the db, in relation to an ID that we are going to supply in GET mode.
<?php
$path = "indirizzo/del/file/";
$name = "nomedelfile.ext";
$size = filesize($path); //calculate file size
header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: post-check=0, pre-check=0', false);
header('Cache-Control: private');
header('Pragma: no-cache');
header("Content-Transfer-Encoding: binary");
header("Content-type: {$path['mime']}");
header("Content-length: {$size}");
header("Content-disposition: attachment; filename=\"{$name}\"");
readfile($path);
exit;
?>
