I am using a custom site build in zend frameword, i also have a wordpress installed in this directory, for example:

www.mywordpressSite.com // here is my wordpress site..
www.mywordpressSite.com/frameWorkSite // here is my framework site..

All i need to get a framwork session inside wordpress theme, i tried by accessing direcct like,

$_SESSION['userId'];

I tried by making a class in framework and by including this in my wordpress site, but in vain..

Any helpful idea is greatly appreciated..

Wordpress doesn't use PHP session ($_SESSION). If you want to use it you need to do at your own. For example:

add_action('init', 'wpse_session_start', 1);
function wpse_session_start() {
    if(!session_id()) {
        session_start();
    }
}

But, if you want is to get the user id of the current user, you can use get_current_user_id():

<?php $user_ID = get_current_user_id(); ?>
