Session Variables

Does anyone know how to get the session variables in v4 when stored in the database? Are they the same as in v3?
I've added the <?php session_start(); ?> and <?php var_dump($_SESSION);?> but only get array(0) { } as the output.

Thanks Alex,
From the helpdesk:
Here is a code you can use
include_once('./amember/library/Am/Lite.php');
echo Am_Lite::getInstance()->getEmail();
//last line will output all available data for logged in user print_r(Am_Lite::getInstance()->getIdentity());

I got an error when trying to access getIdentity(). Instead, I saw that the Lite.php file already stored getIdentity() in getUser(). So if you ever want to see the whole kit 'n' kaboodle:

PHP:

require_once '/home/user/public_html/amember/library/Am/Lite.php'
print_r(Am_Lite::getInstance()->getUser());

Kabam!
