#### Changing the file name when open the pdf file in browser using php code

I have an issue while showing the file in browser. Generally I have pdf file to show (may be other). So first here is my code —

  header('Content-Description: File Transfer');
//              $filename = "myfile.pdf; // header('Content-Disposition: inline; filename=' .$filename);
//                header('Content-Length: ' . strlen(base64_decode($decodedbase64string))); // ob_clean(); // flush(); //decode the image echo base64_decode($decodedbase64string);
