OK, if there are only a limited number of these "pre-defined bits of data"
then the easiest way is probably just output it as plain text (you don't say
what kind of data you're sharing) in an easy to parse format (CSV, XML,
whatever you're comfortable with).

If your webserver is SSL enabled you could just make the data available only
via login on SSL. It's relatively easy to setup the clients to login
automatically. PHP supports encryption if you install the necessary libraries
and configure PHP accordingly (manual > Mcrypt Encryption Functions). However
the client has to be configured similarly so that it can decode the stuff.
