show logout button along with the name of user after successfull login

问题

I am a yiibie, and i am stuck at a point. I have three roles in my project. 1.Admin. 2.Owner 3. Authenticated User. I have a header and a footer widget.In header widget which is the top section has a signup and login link. i want to show my user name and a logout link after his successful login. I do not want to make another widget. i Know the logic, we can use if else. If a user has been logged in, show his name and logout link at the top section(header widget). else if he is a normal user or not logged in show him, signup and login link. Thats it.But how to write code..is the thing i dont know. Plus i am using yii rights and yii user extension too.

Is easy after login you can see the username otherwise you see nothings

<?php  
   if (!Yii::app()->user->isGuest) {
    echo Yii::app()->user->name;
   }
 ?>
