Ask a difficult logout question

Is it difficult to log out? Description: userState (1 is not logged on, 2 is logged on), a login. on the php page, after logging in successfully (saving the COOKIE or SESSION), modify the userState (user status) in the database & nbsp; 2. if the user clicks cancel (clear COOKIE or SESSION), then modify userState & nbsp; & nb in the database to ask a difficult cancellation question?
Note:
UserState (1 is not logged on, 2 is logged on ),
A login. on the php page, after logging in successfully (saving the COOKIE or SESSION), modify the userState in the database (user status) = 2. if the user clicks cancel (clear COOKIE or SESSION), then modify userState = 1 in the database
Q: How can I change this userState to 1 when this user directly closes the page without logging out?
