What are some best practices for handling error codes and returns in PHP scripts, especially when dealing with external APIs like XMLRPC?

When dealing with error codes and returns in PHP scripts, especially when working with external APIs like XMLRPC, it is important to handle potential errors gracefully to prevent unexpected behavior or crashes in your application. One best practice is to check for errors after making API calls and handle them appropriately by logging the error, displaying a user-friendly message, or taking corrective action. 

// Example code snippet for handling error codes and returns in PHP scripts

// Make an API call using XMLRPC
$client = new xmlrpc_client('http://api.example.com/xmlrpc');
$message = new xmlrpcmsg('api.method', array('param1', 'param2'));
$response = $client->send($message);

// Check for errors in the response
if (!$response) {
    // Handle connection error
    echo "Error connecting to API";
    exit;
}

if ($response->faultCode()) {
    // Handle API error
    $errorCode = $response->faultCode();
    $errorMessage = $response->faultString();
    echo "API Error: $errorCode - $errorMessage";
    exit;
}

// Process API response
$data = $response->value();
// Continue with data processing
