restrict to download the pdf files

That is not possible. As Jamie said, reading is downloading. When a user is reading a file, browser is downloading that file to temp. So even if you disable the download button, the user can click "File -> Save As" or copy that file from temp folder.

A solution is to give only a sample (first few pages, for example) to the public, and to access the full, they need to signup. I have no better solution in mind that to manually keep 2 files in the server - full and abstract.

How can I prevent a PDF file from being downloaded or printed with PHP or JavaScript?

I was able to find a solution using ViewerJS and this CSS. The CSS shows a blank page when you try to print (ViewerJS already distorts it to a non-printable state) and ViewerJS prevents you from downloading as a PDF file and instead tries to save as an HTML file.

This meets the requirements of making it just inconvenient enough to discourage users from trying to download the file since the file is always easily accessible on almost any page of the site.

View pdf file in browser instead of downloading

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'));
