PHP to view PDF on a web page and disable user to download

I am going to write a site that allows users to view pdf files, but I do not want them to save the files on their own hard drive due to copy rights. I am learning how to view it using PHP, but I do not know how to disconnect the user so as not to upload files.

Actually, I want to use JavaScript to disable this action, but I get suggestions from other people not to do this because it annoys the user.

Therefore, any suggestion or help would be greatly appreciated.
