title: Zend Framework: Can i just get GET params?
body: <p>In Zend Framework, most of the time to get a param, i will use</p>
  
  <pre><code>// from controller
  $this-&gt;getRequest()-&gt;getParam('key');
  </code></pre>
  
  <p>but how can i get just GET params using the 'Zend' way? Or do i just use <code>$_GET</code>? Is there any difference between </p>
  
  <pre><code>$this-&gt;getRequest()-&gt;getParam('key');
  </code></pre>
  
  <p>vs </p>
  
  <pre><code>$_GET['key'];
  </code></pre>
