download.php 
<?php 

    $file= $_GET['name'];// make sure it should be a correct path 
    if (file_exists($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; 
    }
