header("Content-type: application/pdf");

Answer

You need to change the Content-disposition to inline.

Change

header("Content-disposition: attachment;     
filename=".basename('theme/assets/pdf/ci.pdf'));

To:

header("Content-disposition: inline;     
filename=".basename('theme/assets/pdf/ci.pdf'));
