What are the advantages and disadvantages of using getter/setter methods instead of func_get_args() in a PHP session management system?

Using getter/setter methods in a PHP session management system provides better encapsulation and control over the session data. It allows for validation and manipulation of data before setting or getting it, ensuring data integrity. However, using func_get_args() directly can lead to less readable and maintainable code, as well as potential security vulnerabilities if not handled properly. 

class SessionManager {
    private $sessionData = [];

    public function setSessionData($key, $value) {
        // Perform validation or manipulation of data if needed
        $this->sessionData[$key] = $value;
    }

    public function getSessionData($key) {
        // Perform any additional logic before returning the data
        return $this->sessionData[$key];
    }
}

// Example usage
$sessionManager = new SessionManager();
$sessionManager->setSessionData('user_id', 123);
$userID = $sessionManager->getSessionData('user_id');
