Inject your authentication object into a helper.

First, define the helper:

class My_View_Helper_LoginStatus extends Zend_View_Helper_Abstract
{
protected $_auth;

public function loginStatus()
{
return $this->getAuth()->hasIdentity();
}

public function setAuth(Zend_Auth $auth)
{
$this->_auth = $auth;
return $this;
}

public function getAuth()
{
return $this->_auth;
}
}

Then, in your bootstrap, push your auth object into the helper:

// First, get the helper object:
$helper = $view->getHelper('loginStatus');

// Now do the dependency injection:
$helper->setAuth($auth);

In your view scripts, you can then utilize the helper:

<?php if ($this->loginStatus()): ?>
Welcome!
<?php else: ?>
Please log in!
<?php endif ?>
