Creating password protected RAR files in PHP?

I need to dynamically create a password protected RAR file with a file inside it. The password would be the same as that of the user downloading the file.

Alternatively, I need a way to password protect a PDF document, also dynamically.

Any help you can give would be much appreciated, as I've looked all over and found no luck.

If your host allows you to execute files and if it has RAR installed, you can do it with the following command (change it as necessary):

exec("rar a -p[password] archive.rar file1.ext file2.ext");

Change [password] with the password (e.g. if the password was "password" then it would be -ppassword).
