I am looking for information on how to create and run a simple server game that will take turn information from one user, do some number crunching and pass the resultant information on to the other players in the game.
What I am looking for is a push in the right direction. While I have been coding for the iPhone for almost two years now, my server experience is limited to making a URL request to a PHP script that pulls information from a database and return it to the iPhone requesting the information. I have no idea how to take information from an iPhone and send it to other specific iPhone or players.
Any help you can give is greatly appreciated. Tutorials would be nice but even just a hint of how to go about doing this would be fantastic.
Thanks.
