PHP to view PDF on web page and disable user to download
I'm going to write a site that lets users to view pdf files but I don't want them to save the files to their own hard drive due to the copy right law. I'm researching how to view it by using PHP, but I have no idea how to disable user not to download the files.
So any suggestion or help would be very much appreciated.

I hope I am not very late to reply. But here's is something you can do to prevent the users. Use iFrame to display your PDF and make sure that you are displaying using Google. I used the following code :
Here you can simply change the
url=http://www.tutorialspoint.com/php/php_tutorial.pdfand replace it by your own URL where you kept your PDF.
