Teamspeak 3 PHP Framework - Give User Servergroup by IP

Hey,

I want a Script on my Website with Ts3 PHP Framework that gets the IP of the user browsing the site and gives
the User on my Teamspeak with the same IP a server group.
I got no idea how to do this, someone can write me this little script?

Thanks!
