I have this code for save a session to a db table.

'service_manager' => array(
    'factories' => array(
        'Zend\Session\SessionManager' => function (\Zend\ServiceManager\ServiceManager $sm) {
            $sessionConfig = new \Zend\Session\Config\SessionConfig();
            $sessionConfig->setOptions(
                array(
                    'use_cookies' => true,
                    'name' => 'ed2',
                    'gc_maxlifetime' => 1728000
                )
            );

            /* @var $adapter \Zend\Db\Adapter\Adapter */
            $adapter = $sm->get('Zend\Db\Adapter\Adapter');
            $tableGateway = new \Zend\Db\TableGateway\TableGateway('session', $adapter);
            $saveHandler  = new \Common\Session\SaveHandler\DbTableGateway(
                $tableGateway,
                new \Zend\Session\SaveHandler\DbTableGatewayOptions()
            );

            $sessionManager = new \Zend\Session\SessionManager($sessionConfig);
            $sessionManager->setSaveHandler($saveHandler);
            $sessionManager->start();
            return $sessionManager;
        },
    )
)

'db' => array(
    'driver'    => 'Pdo_Mysql',
    'database'  => 'release',
    'username'  => 'username',
    'password'  => 'password',
    'hostname'  => '127.0.0.1',
    'driver_options' => array(
        PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
    )
),
'service_manager' => array(
    'factories' => array(
        'Zend\Db\Adapter\Adapter' => function (\Zend\ServiceManager\ServiceManager $serviceManager) {
            $adapterFactory = new Zend\Db\Adapter\AdapterServiceFactory();
            $adapter = $adapterFactory->createService($serviceManager);

            Zend\Db\TableGateway\Feature\GlobalAdapterFeature::setStaticAdapter($adapter);

            return $adapter;
        }
    )
)
