For creating yii session

Yii::app()->session['userid'] = "value";

You can get value like this

$sleep = Yii::app()->session['userid'];

And unset session like

unset(Yii::app()->session['userid']); # Remove the session

In case of user signs out , you have to remove all the session.

Yii::app()->session->clear();

After this, you need to remove actual data from server

Yii::app()->session->destroy();
