Simply, namespace is like name of groups of associative arrays, keyed by strings. For practice, we use our previous practice.

Ok, we want to count number of a particular page request form a visitor. See this picture:

To do this, open your UserController.php within application/controllers. Include Zend/Session/Namespace.php at first line after delimeter.

require_once 'Zend/Session/Namespace.php';

Edit loginFormAction() method become like this:

  public function loginFormAction()
  {
    $request = $this->getRequest();  
	
    $ns = new Zend_Session_Namespace('HelloWorld');
    
	if(!isset($ns->yourLoginRequest)){
	  $ns->yourLoginRequest = 1;
	}else{
	  $ns->yourLoginRequest++;
	}
    
	$this->view->assign('request', $ns->yourLoginRequest);
	$this->view->assign('action', $request->getBaseURL()."/user/auth");  
    $this->view->assign('title', 'Login Form');
    $this->view->assign('username', 'User Name');	
    $this->view->assign('password', 'Password');	
	    
  }

At line 5, we define object of namespace. The namespace, we named "HelloWorld". It is like $_SESSION['HelloWorld']. You can put name such as mynamespace, myapplication, etc.

Next, at line 7, we check value of $ns->yourLoginRequest. It is like $_SESSION['HelloWorld']['yourLoginRequest']. Next, modify loginform.phtml within application/views/scripts/user. Update become like this:

<? include "header.phtml"; ?>
  <h1><?=$this->escape($this->title);?></h1>
  You have entered this page: <?=$this->escape($this->request);?> time(s).
  <form method='post' action='<?=$this->escape($this->action);?>'>
  <table>
    <tr>
	  <td><?=$this->escape($this->username);?></td>
	  <td><input type='text' name='username'></td>
	</tr>
    <tr>
	  <td><?=$this->escape($this->password);?></td>
	  <td><input type='password' name='password'></td>
	</tr>	
  </table>
  <input type='submit' name='login' value='Login'>
  </form>
<? include "footer.phtml"; ?>

Now, point your browser to http://localhost/test/zend/helloworld/web_root/user/loginform. You may get screen like picture above.

Ok, try again for userPageAction() at controller. Update become like this:

  public function loginFormAction()
  {
    $request = $this->getRequest();  
	
    $ns = new Zend_Session_Namespace('HelloWorld');
    
	if(!isset($ns->yourLoginRequest)){
	  $ns->yourLoginRequest = 1;
	}else{
	  $ns->yourLoginRequest++;
	}
    
	$this->view->assign('request', $ns->yourLoginRequest);
	$this->view->assign('action', $request->getBaseURL()."/user/auth");  
    $this->view->assign('title', 'Login Form');
    $this->view->assign('username', 'User Name');	
    $this->view->assign('password', 'Password');	
	    
  }

Then, update its view at application/views/scripts/user/userpage.phtml:

<? include "header.phtml"; ?>
<h1>Hello, <?=$this->escape($this->real_name);?></h1>
You have entered this page: <?=$this->escape($this->request);?> time(s).
<a href='<?=$this->escape($this->urllogout);?>'>Logout</a>
<? include "footer.phtml"; ?>
