Hey all,
I'm planning on making an online 2-player game with PHP for a class project. I'm pretty good with PHP now, but I have no idea how to do this. The 2 main functions I want are:

1. Once a user is logged in, he/she is able to see a list of all the others who are logged in as well.

2. Being able to click on another person's user name or sending an instant message in order to initiate a game.

3. Once the game has begun, both players will be looking at the same playing field, and changes will be represented on both player's screens.

How easy/hard will this be to do within 4 weeks? Can anyone point me to some examples or good tutorials for this type of PHP code?

Thanks a bunch!
