How to format Serialized Zend_Service_Twitter response

When I use OAuth to connect an application to a twitter account I put the access token and the user data in my database as follow:

$this->consumer = new Zend_Oauth_Consumer($this->configTwitter);

    if(!empty($_GET) && isset($_SESSION['TWITTER_REQUEST_TOKEN']))
    {
        $token = $this->consumer->getAccessToken($_GET, unserialize($_SESSION['TWITTER_REQUEST_TOKEN']));
        // Get user info
        $twitter = new Zend_Service_Twitter(array(
            'username' => $token->screen_name,
            'accessToken' => $token,
            'callbackUrl' => $this->_getParam('SettingsWebsiteUrl').'/news/index/connecttwitter',
            'consumerKey' => 'XXXXXX',
            'consumerSecret' => 'XXXXXXX'
         ));
        $response = $twitter->account->verifyCredentials();
        // place in database
        $this->NewsService->TokenSocialMedia(
            $token,
            'twitter',
            serialize($response)
        );
        $_SESSION['TWITTER_REQUEST_TOKEN'] = null;
        $this->_helper->flashMessenger(array('message' => $this->view->translate('The CMS is successfully connected to your twitter account'), 'status' => 'success'));
        $this->_helper->redirector('settings', 'index');
    }
    else
    {
        $token = $this->consumer->getRequestToken();
        $_SESSION['TWITTER_REQUEST_TOKEN'] = serialize($token);
        $this->consumer->redirect();
    }

This works fine. The response looks like this below and I have no clue of how to format this and display it to the user. Only thing I want is to store the twitter id, twitter name (not screen_name) and the image url.

How do I need to format the data, or how can I store the data better?

If all you want to store is their image url, then you just need their username, then use this:

http://img.tweetimag.es/i/oprah_o

where oprah_o is the username.

You don't need to use OAuth and Zend_Service_Twitter to do that. If you want to be able to get data from a non public feed, or publish tweets to their accounts, that's where you need Zend_Service_Twitter.

If you want to get data from that resultset, just do:

$result_obj = unserialize($token);
