title: Zend 1 not working with psr-4 namespaces
body: <p>I am working on zend framework 1 But I want to use \ instead of _</p>
  
  <p>Like </p>
  
  <pre><code>class IndexController extends Zend_Controller_Action 
  </code></pre>
  
  <p>This is working fine but when I changed this by</p>
  
  <pre><code>class IndexController extends \Zend\Controller\Action
  </code></pre>
  
  <p>Then its giving me a error </p>
  
  <pre><code>Fatal error: Cannot redeclare class Zend_Controller_Action in /var/www/flipit_application/vendor/zendframework/zendframework1/library/Zend/Controller/Action.php on line 43
  </code></pre>
  
  <p>I have created the namespaces in composer </p>
  
  <pre><code>"autoload": {
          "psr-4": {
              "Zend\\": "vendor/zendframework/zendframework1/library/Zend/"
          }
      },
  </code></pre>
  
  <p>So how Can use these namespaces in code </p>
  
  <p><strong>Is this possible in Zend Framework1?.</strong></p>
