Here is the general code I am trying

<?php
        // Init PHP Sessions
        session_start();

        $fb = new Facebook([
          'app_id' => 'xxxxxxxxx',
          'app_secret' => 'xxxxxxxxxxx',
        ]);

        $helper = $fb->getRedirectLoginHelper();

        if (!isset($_SESSION['enter api key here'])) {
          $_SESSION['enter api key here'] = null;
        }

        if (!$_SESSION['enter api key here']) {
          $helper = $fb->getRedirectLoginHelper();
          try {
            $_SESSION['enter api key here'] = (string) $helper->getAccessToken();
          } catch(FacebookResponseException $e) {
            // When Graph returns an error
            echo 'Graph returned an error: ' . $e->getMessage();
            exit;
          } catch(FacebookSDKException $e) {
            // When validation fails or other local issues
            echo 'Facebook SDK returned an error: ' . $e->getMessage();
            exit;
          }
        }

        if ($_SESSION['enter api key here']) {
          //echo "You are logged in!";

        // Initialize a new Session and instantiate an API object
        Api::init(
          'xxxxxxxxx', // App ID
          'xxxxxxxxx', //app_secret
          $_SESSION['enter api key here'] // Your user access token
        );
