 6 Header( "Content-type: application/octet-stream "); 
 7 Header( "Accept-Ranges: bytes "); 
 8 Header( "Accept-Length: " .filesize($filename));
 9 header( "Content-Disposition: attachment; filename= {$date}.doc"); 
10 echo file_get_contents($filename);
11 readfile($filename); 
12 }
13 downfile();
