Are there any specific guidelines or restrictions to keep in mind when registering a Facebook App in PHP to avoid errors related to protocol information in the App Domain?

When registering a Facebook App in PHP, it is important to ensure that the protocol information in the App Domain matches the protocol used in your website URL. This can help avoid errors related to mismatched protocols and ensure that your app functions correctly when communicating with Facebook's API. 

// Correctly set the protocol for the App Domain to avoid errors
$fb = new Facebook\Facebook([
  'app_id' => 'your_app_id',
  'app_secret' => 'your_app_secret',
  'default_graph_version' => 'v11.0',
  'default_access_token' => 'your_access_token',
  'app_url' => 'https://yourwebsite.com',
  'app_domain' => 'https://yourwebsite.com',
]);
