Auto logout old session on new login

[shivsingh7150]

Hello

I am want to make a hook that auto logout old session from same user.

I already know IP based system but i need it should work even if client logged in into other browser on same computer and same IP.

So we are storing session of login on database then we can load that session and destroy it.

i will use it with:

<?php
add_hook('ClientLogin', 1, function($vars) {
    // Perform hook code here...
});
