PS: This code runs under the win system no problem, Feng Ge pro-test available. If you use linux or other systems, you need to test it yourself.

$filename = "./".$_REQUEST['name']; // Here is the specific path of Feng Ge , As long as $filename Is the full path of the file to be downloaded .
if (!is_file($filename)) {// Detect the existence of a file .
 die(' The downloaded file seems to be similar to TM Who eloped !');
}
$filepath = str_replace('\\', '/', realpath($filename));
$filesize = filesize($filepath);
$filename = substr(strrchr('/'.$filepath, '/'), 1);
$extension = strtolower(substr(strrchr($filepath, '.'), 1));
       // use this unless you want to find the mime type based on extension, File suffix format , Do not explain .
$mime = array('application/octet-stream');
header('Content-Type: '.$mime);
