Killing session by id?

[Sinkadus]

Hi!

I'm handeling logins with sessions. When a certain account has reached its' maximun allowed simultaneous logins I want to kill the first session. What I would like to do is kind of:

session_destory($session_id);

But that doesn't work of cource. Is there any way to kill a certain session and not just the 'current' one? If so, please let me know.

Not in a php page requested by a brower. It passes it's own session ID and that's all that instance of php should be allowed to work with.
