How to check whether the user is already logged in on different ip/locations

Question

I want to check whether the same user is logged in more than one locations over different IP and if a user already logged in then the previous session will be destroyed.

Is there any solution on YII framework?

Currently I am trying to develop this project on YII framework.

you can do like this

add a "last_session_ip" column to your userdata table
when a user logs in, update its last_session_ip field with its current ip
create a function like loginauth() which will compare the current ip with db value . if not same destroy the session

this is not a proper solution but this can put you on right track.

User can use static ip from there service provider. In this case also multiple login happens – Sanhosh john Jun 16 '15 at 13:11

Without any storage you can't do this. you should use database for logging the log in history and when user log in again, compare the user IP and other things you want by new user which signed in and do what ever you want to that user.
