Zend Framework - Navigation set current page title with tag title on navigation.xml

/ Published in: PHP
Save to your folder(s)
If you have Zend_Navigation in your application, you will use navigation.xml. This code set the page title ($this->view->headTitle()) with the current page title in navigation.xml.
$navigation->current() doesn't work in my opinion.
