What are common challenges when working with the Facebook API in PHP?

One common challenge when working with the Facebook API in PHP is handling access tokens and authentication. To solve this, you need to properly authenticate your application with Facebook and obtain a valid access token to make API requests. 

// Example code to authenticate with Facebook and obtain access token
$fb = new Facebook\Facebook([
  'app_id' => 'your_app_id',
  'app_secret' => 'your_app_secret',
  'default_graph_version' => 'v11.0',
]);

$helper = $fb->getRedirectLoginHelper();

$permissions = ['email']; // optional permissions
$loginUrl = $helper->getLoginUrl('https://your-redirect-uri.com', $permissions);

echo '<a href="' . htmlspecialchars($loginUrl) . '">Log in with Facebook!</a>';
