Answer 1

I will suggest You to integrate using as a model . Unzip you facebook sdk . Put the unzipped folder in application/models . Rename the sdk folder to facebook . Now you can use the following code to instantiate FB and get a kick-start . You can use this model for querying facebook .

define('FACEBOOK_SDK_V4_SRC_DIR',APPPATH.'/models/facebook/');

require_once("facebook/autoload.php");

        use Facebook\FacebookSession;
        use Facebook\FacebookRequest;
        use Facebook\GraphUser;
        use Facebook\FacebookRequestException;
        use Facebook\FacebookRedirectLoginHelper;



class facebook_model extends CI_Model 
{

public $fb ;
public $access_token ;

public function __construct()
{
    parent::__construct();
}



public function facebookInit()
{
      $this->fb = new Facebook\Facebook([
                                     'app_id'                => 'APP_ID',
                                     'app_secret'            => 'APP_SECRET',
                                     'default_graph_version' => 'v2.5',
                                    ]); 
      return $this->fb ;                        

}
 //function to get login url for your app . Just create a controller which     handles redirects after facebook login 

public function loginUrl()
{
    $helper = $this->facebookInit()->getRedirectLoginHelper();
    $permissions = ['email','user_friends']; // Optional permissions

    $loginUrl = $helper->getLoginUrl(site_url()."/FBController/", $permissions);
    return $loginUrl ;  


}


}

Install php sdk v5 in codeigniter with composer https://www.sammyk.me/upgrading-the-facebook-php-sdk-from-v3-x-to-v5#installation-with-composer

create a controller and paste this code

$fb = new Facebook\Facebook([
    'app_id'     => 'app_id',
    'app_secret' => 'app_secret',
    'default_graph_version' => 'v2.4',
    'default_access_token' => 'access_token'
    ]);

    $response = $fb->get('/page_id');
    $body = $response->getBody();

$body is an array, send it to your views for show your data.
