title: Get all parameters after action in Zend?
body: <p>When I call a router like below in Zend:</p>
  
  <p><code>coupon/index/search/cat/1/page/1/x/111/y/222</code></p>
  
  <p>And inside the controller when I get <code>$this-&gt;_params</code>, I get an array:</p>
  
  <pre><code>array(
      'module' =&gt; 'coupon',
      'controller' =&gt; 'index',
      'action' =&gt; 'search',
      'cat' =&gt; '1',
      'page' =&gt; '1',
      'x' =&gt; '111',
      'y' =&gt; '222'
  )
  </code></pre>
  
  <p>But I want to get only:</p>
  
  <pre><code>array(
      'cat' =&gt; '1',
      'page' =&gt; '1',
      'x' =&gt; '111',
      'y' =&gt; '222'
  )
  </code></pre>
  
  <p>Could you please tell me a way to get the all the <code>params</code> just after the <code>action</code>?</p>
