I am showing PDF, Video file preview in my web application, but i want to give only read access to users, no one can`t download PDF & video files, I want to prevent users, how can we prevent users to download it using PHP ? only they can view, please share you ideas as soon as.
Thanks
Any content that is shown on the client's side, technically speaking, already downloaded to the user's machine. If the user is seeing the PDF file - it's already been downloaded.
For video: it's not that straightforward, you can organize a streaming of the video. It'll be fairly more complex for the user to download it as one file, but still, can be captured.
