I have a dating website that I am developing the front-end for. It is pretty much done, but I wanted to know if anyone can refer me to a good tutorial on how to use PHP to limit the number of profiles they can view before being forced to log-in/register? I don't really do PHP coding, but I do "dabble". I need to know what I have to do to the code of my "sign_in" page to display a message that says something like "sorry, you must be signed in to view more profiles". Where should I start on this? Tutorials?
