2 Users...

I am currently in the process of making an RPG. I have users sign up on a registration form and after signing up, it inserts information into the database including username and password. Now to log in, all it does is simply compare the username and password that the user has inputted to a username and password in the database and if they match, they successfully log in. Now, i have made a monster battling system where the user fights with their "stats" against imaginary monsters. Now the next step i want to do is to have it so that 2 users can fight against each other. I have the database information but how would i have it so that when various users login, they can fight each other in a 1:1 battle? For example, lets say Bob logged in, and on another computer, Joe logged in. They both have their own stats which are stored into the database corresponding to the info in the database. Now Joe and Bob want to battle. How would i do this? Any help would be appreciated.

sneaky bit of code coming up - but i cant quite remember it so i'll give the outline and you do the legwork, k? 😉

what you do is this;

1. use sessions. At the top of each page, you need to call session_cache_expire(0). The 0 specifies that sessions will die as soon as the browser is closed by the user. then call session_start() to keep the session alive on that page

2. when each user logs in, store the session id (session_id()) in the database

3. open the directory where session vars are stored. This path is stored in session_save_path()

4. read in the list of files from the directory. These will be named sess_SESSION_ID (where session_id is umm the session id!)

5. pick two files at random - these both correspond to users online. If you dont put in the session_cache_expire above, the session will die 180 mins after the browser is closed - so the user may have gone hours before...

6. because the session id was stored in the db, you can get the user info for that session, and send his/her stats into battle!
