What are some potential challenges when using the Facebook API to retrieve likes and shares in PHP?

One potential challenge when using the Facebook API to retrieve likes and shares in PHP is handling authentication and permissions. You need to ensure that your application has the necessary permissions to access this data. Another challenge is handling rate limits imposed by the API, which may restrict the number of requests you can make within a certain time frame. Additionally, you need to handle errors gracefully to prevent your application from crashing if there are issues with the API response. 

// Example code for handling authentication and permissions
$fb = new Facebook\Facebook([
  'app_id' => 'your_app_id',
  'app_secret' => 'your_app_secret',
  'default_graph_version' => 'v11.0',
]);

$helper = $fb->getRedirectLoginHelper();

$permissions = ['user_likes', 'user_shares']; // Specify the necessary permissions

try {
  $accessToken = $helper->getAccessToken();
} catch(Facebook\Exceptions\FacebookResponseException $e) {
  // Handle error
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  // Handle error
}

if (isset($accessToken)) {
  // Use the access token to make API requests
} else {
  // Redirect the user to the login URL with required permissions
  $loginUrl = $helper->getLoginUrl('https://your-redirect-uri.com', $permissions);
}
