	parent::__construct();
	include_once APPPATH."libraries/twitter-oauth-php/twitteroauth.php";
}

Step 2: Twitter button on click and redirect controller function like (index())

public function index(){
   $userData = array();

   $consumerKey = ''; //Insert_Twitter_API_Key
   $consumerSecret = ''; //Insert_Twitter_API_Secret
   $oauthCallback = base_url().'login/';

   $sessToken = $this->session->userdata('token');
   $sessTokenSecret = $this->session->userdata('token_secret');

   $sessStatus = $this->session->userdata('status');
   $sessUserData = $this->session->userdata('userData');

   if(isset($sessStatus) && $sessStatus == 'verified')
   {
	   $connection = new TwitterOAuth($consumerKey, $consumerSecret, $sessUserData['accessToken']['oauth_token'], $sessUserData['accessToken']['oauth_token_secret']); 
	   $data['tweets'] = $connection->get('statuses/user_timeline', array('screen_name' => $sessUserData['username'], 'count' => 5));
	   $userData = $sessUserData;
	   echo "<pre>";
	   print_r($userData);
	   die;
   }
   elseif(isset($_REQUEST['oauth_token']) && $sessToken == $_REQUEST['oauth_token'])
   {
	   $connection = new TwitterOAuth($consumerKey, $consumerSecret, $sessToken, $sessTokenSecret);
	   $accessToken = $connection->getAccessToken($_REQUEST['oauth_verifier']);

		   $userInfo = $connection->get('account/verify_credentials');

		   $name = explode(" ",$userInfo->name);
		   $first_name = isset($name[0])?$name[0]:'';
		   $last_name = isset($name[1])?$name[1]:'';
		   $userData = array(
			   'oauth_provider' => 'twitter',
			   'oauth_uid' => $userInfo->id,
			   'username' => $userInfo->screen_name,
			   'first_name' => $first_name,
			   'last_name' => $last_name,
			   'locale' => $userInfo->lang,
			   'profile_url' => 'https://twitter.com/'.$userInfo->screen_name,
			   'picture_url' => $userInfo->profile_image_url
		   );

		   $userData['accessToken'] = $accessToken;
		   $this->session->set_userdata('status','verified');
		   $this->session->set_userdata('userData',$userData);
		   echo "<pre>";
		   print_r($userData);
		   die;
   }
   else
   {
	   $this->session->unset_userdata('token');
	   $this->session->unset_userdata('token_secret');

	   $connection = new TwitterOAuth($consumerKey, $consumerSecret);
	   $requestToken = $connection->getRequestToken($oauthCallback);

	   $this->session->set_userdata('token',$requestToken['oauth_token']);
	   $this->session->set_userdata('token_secret',$requestToken['oauth_token_secret']);

	   $twitterUrl = $connection->getAuthorizeURL($requestToken['oauth_token']);
	   $data['oauthURL'] = $twitterUrl;
   }

   $data['userData'] = $userData;
   $this->load->view('login',$data);
}

Step 3: Session destroy Code

public function logout() 
{
	$this->session->unset_userdata('token');
	$this->session->unset_userdata('token_secret');
	$this->session->unset_userdata('status');
	$this->session->unset_userdata('userData');
	$this->session->sess_destroy();
	redirect('/login');
}

Output

Array
(
    [oauth_provider] => twitter
    [oauth_uid] => 11235064246243
    [username] => HARDIKDAYANI
    [first_name] => HARDIK
