If the web browser is closed none of your code is going to run.

You can log them out on browser close set this in ./application/config/config.php.

PHP Code:

$config['sess_expiration'] = 0; 


That tells the browser to close the session on exit.

What did you Try? What did you Get? What did you Expect?
