Actually you might need to search on google before posting your question on stack overflow regarding Zend_Session_Namespace. There are no. of article available on google. But still here is some sort of basic guidance for you about Zend_Session_Namespace.

The Zend Framework provides advanced session handling using the Zend_Session component. Using this component, you no longer need to access PHP’s $_SESSION global variable.

Zend_Session uses namespaces to store your session data. That is, when you want to read or write session data you must first specify a namespace. This allows you to easily store different session data without worrying too much about other values stored in the session.

Example:

<?php
    require_once('Zend/Session.php');
    $session = new Zend_Session_Namespace('identity');

    //You can used it like this:

    $username= $session->username;
    $userid= $userid;
?>

Read Zend Session Namespace from zend framework’s documentation for more details

$a=new Zend_Session_Namespace(Zend_Registry::get('session_variable'));

The above code means : You set your session in zend registry by using zend_registry’s set method somewhere (might be in bootstrap) and you are accessing it by using zend_registry's get method.

If you are new in Zend Framework I recommend you to please go through following tutorial.
