title: how to use a function within same function zend framework
body: <p>Hii...</p>
  
  <p>I have a function something like this...</p>
  
  <pre><code>class Zend_View_Helper_RenderUOList extends Zend_View_Helper_Abstract {
  
      public function makeUOList($inputArray, $main = true, $id ="", $class="")
      {
        ------
        ------
        ------
        $output .= "&lt;li&gt;" . $value['name'] . "\n";
        $output .=  makeUOList($value, false, '', '');
        $output .= "&lt;/li&gt;\n";
  </code></pre>
  
  <p>and I am trying to call the same function within the function and I am getting a error message as 
  Fatal error: Call to undefined function makeUOList() in C:\dev\workspaces\adxweb\library\Zend\View\Helper\RenderUOList.php on line 99</p>
  
  <p>Any help where I am going wrong... thanx in advance.</p>
