如何检查用户是否已登录不同的IP /位置

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.

Answer 1

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.
