What are some best practices for integrating Facebook SDK into a website, especially for a video platform with database interactions?

When integrating the Facebook SDK into a website, especially for a video platform with database interactions, it's important to properly authenticate users, handle user permissions, and track user interactions with videos. One best practice is to use the Facebook PHP SDK to handle authentication and user data retrieval, and to store user information in the database for personalized experiences. 

```php
<?php
require_once 'vendor/autoload.php'; // Include the Facebook PHP SDK

$fb = new Facebook\Facebook([
  'app_id' => 'your_app_id',
  'app_secret' => 'your_app_secret',
  'default_graph_version' => 'v10.0',
]);

$helper = $fb->getRedirectLoginHelper();

$permissions = ['email', 'user_videos']; // Specify the required permissions

try {
  if (isset($_SESSION['facebook_access_token'])) {
    $accessToken = $_SESSION['facebook_access_token'];
  } else {
    $accessToken = $helper->getAccessToken();
  }
} catch(Facebook\Exceptions\FacebookResponseException $e) {
  // When Graph returns an error
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  // When validation fails or other local issues
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}

if (isset($accessToken)) {
  // Logged in
  $_SESSION['facebook_access_token'] = (string) $accessToken;

  // Get user details
  $response = $fb->get('/me?fields=id,name,email', $accessToken);
  $user = $response->getGraphUser();

  // Store user details in the database
  // Example: $db->query("INSERT INTO users (facebook_id, name, email) VALUES ('{$user->getId()}', '{$user->getName()}', '{$user->getEmail()}')");

  // Handle video interactions
  // Example: $db->query("INSERT INTO video_interactions (user_id, video_id, action) VALUES ('{$user->getId()}', '{$video_id}', 'play')");

  // Redirect or display content based on user status
} else {
  // Not logged in, redirect to Facebook login page
  $loginUrl = $helper->getLoginUrl('https://yourwebsite.com/fb-callback.php', $permissions);
  echo '<a href="' . $login
