title: Equivalent of CakePHP $this->params to retrieve all POST/GET on Yii?
body: <p>On CakePHP we can get ALL POST/GET using</p>
  
  <pre><code>$this-&gt;params
  </code></pre>
  
  <p>On Yii, I am not sure if it has a equivalent. Only saw if I want to get one field value regardless if (POST/GET), but I need to specify it.</p>
  
  <pre><code>Yii::app()-&gt;request-&gt;getParam('email')
  </code></pre>
