if (!file_exists ($file _dir. $name)) {
Header ("content-type:text/html; Charset=utf-8 ");
echo "File not found!";
Exit
} else {
$file = fopen ($file _dir. $name, "R");
Header ("Content-type:application/octet-stream");
Header ("Accept-ranges:bytes");
Header ("Accept-length:". FileSize ($file _dir. $name));
Header ("content-disposition:attachment; Filename= ". $name);

$file _name=$_get[' FileName ';
$file _dir=$_get[' Filedir '];
$FileId =$_get[' FileId '];
$file _dir = $file _dir. " /";
if (!file_exists ($file _dir. $file _name)) {//check if file exists

Header ("Accept-length:". FileSize ($file _dir. $file _name));
Header ("content-disposition:attachment; Filename= ". $file _name);
