Force file download

Some files, such as mp3, are generally played throught the client browser. If you prefer forcing download of such files, this is not a problem: The following code snippet will do that job properly.

01.function downloadFile($file){
02.$file_name = $file;
03.$mime = 'application/force-download';
04.header('Pragma: public');   // required
05.header('Expires: 0');       // no cache
06.header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
07.header('Cache-Control: private',false);
08.header('Content-Type: '.$mime);

09.header('Content-Disposition: attachment; filename="'.basename($file_name).'"');

10.header('Content-Transfer-Encoding: binary');
11.header('Connection: close');
12.readfile($file_name);       // push it out
13.exit();
14.}
