What are the advantages of using global exceptions with return codes for error handling?

Global exceptions with return codes for error handling provide a centralized way to handle errors throughout an application. By using exceptions, developers can easily catch and handle errors in a structured manner, improving code readability and maintainability. Additionally, return codes allow for more granular control over error handling, enabling developers to easily distinguish between different types of errors and take appropriate action. 

try {
    // code that may throw an exception
    if ($errorCondition) {
        throw new Exception('An error occurred.', 500);
    }
} catch (Exception $e) {
    // handle the exception
    echo 'Error: ' . $e->getMessage();
    // return the error code
    return $e->getCode();
}
