Zend Session example

<?php

/*in the Bootstrap.php file in application/ folder put this code to initiate the session:*/

protected function _initSession()
{
    $session = new Zend_Session_Namespace('your-project-name-here', true);
    $session->setExpirationSeconds(7*86400); // expire in 7 days
    Zend_Registry::set('session', $session);
}

/* to use it to store data between requests: */
public function exampleFirstAction() {
    $session = Zend_Registry::get('session');

    // set data in session
    $session->foo = 'bar';
}

public function exampleSecondAction() {
    $session = Zend_Registry::get('session');

    // get data from session in other place
    if (isset($session->foo)) {
        echo $session->foo;
    }
}
