please read about php header.
this is the code i use to download file

PHP

header("Pragma: public"); // required
	header("Expires: 0");
	header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
	header("Cache-Control: private",false); // required for certain browsers
	header("Content-Type: $ctype"); //$ctype="application/force-download";
	header("Content-Disposition: attachment; filename=".$base.";" );//$base="x.pdf"
	header("Content-Transfer-Encoding: binary");
	header("Content-Length: ".@filesize($filename));
	@readfile($rfilename);
	unlink($rfilename);//delete after download

and remember if you echo or send any other data your pdf file will be corrupted
