you can have serveral mistakes check (and debug) try this

  <?php      $file = absolute_path_where_pdf_is_stored.'/my.pdf'; //replace *absolute_path_where_pdf_is_stored* path       if (file_exists($file)) {          header('content-description: file transfer');          header('content-type: application/octet-stream');          header('content-disposition: attachment; filename='.basename($file));          header('expires: 0');          header('cache-control: must-revalidate');          header('pragma: public');          header('content-length: ' . filesize($file));          readfile($file);          exit;   } else {       die("file [".$file."]" don't exists!");   }  ?>
