title: RBAC implementation in Yii framework
body: <p>I am following the book 'Agile Web Application Development with Yii 1.1 and PHP5' for implementation of Rbac in Yii framework. I am a facing a problem in page 210 of the book which says:</p>
  
  <p>"One other small change we made as to add a simple link from the project details
  page so we could access this form form the application. The following line was
  added to the project show.php view file's list of link options:</p>
  
  <pre><code>&lt;?php 
  echo CHtml::link('Add User To Project',
                   array('adduser','id'=&gt;$model-&gt;project_Id));
  ?&gt;
  </code></pre>
  
  <p>This gives us access to the new form.</p>
  
  <p>Can anyone tell me what does the line mean and where to implement it??</p>
