I m using zend.
I want to define the below code outside the controller class & access in different Actions.
$user = new Zend_Session_Namespace(\'user
You can store the user in many ways and access it in more clean manner. You can store it in Zend_Registry and then use Zend_Registry::get('user') where you need to retrieve the user. You can also store it as a parameter of request object, and then in a controller simply do $user = $this->_getParam('user');
If you need access to the user array in many controllers that inherit from the SystemadminController, what you can do is store it as a protected property of the SystemadminController (eg. protected $_user). Then all you need to do in child controllers is access $this->_user.
