One user registration/login form for more than one website

How do i intergrate user registration for more than one website,i mean i want my users to be able to switch from one site to another without re-registering.

if you want to use the same user info for multiple websites, you need to have all websites use the same database that contains your user's table.

if you want users to be able to log in on one site and remain logged in on another, this is a much trickier task. it's achievable, but is several orders of magnitude more complex than simply sharing user accounts over sites.

all in all i just want my users to register once and be able to login to my defferent websites using the same login info,but i don,t have any idea how to make websites that share the same database:p

If the databases are on the same server just point the db connection file to the same database for each site for doing the login check. If they are on different servers it is basically the same thing except you have to setup the databases to allow remote connections and use the server address in replace of "localhost" usually. I have not done many remote connections can't remember how many steps are actually involved but I don't think it was hard.
