How can the use of magic methods like __call() and call_user_func_array() impact the design of a PHP class when extending the MySQLi class?

When extending the MySQLi class in PHP, using magic methods like __call() and call_user_func_array() can impact the design by allowing for dynamic method calls and handling of undefined methods. This can make the code more flexible and easier to maintain. By implementing these magic methods, you can handle method calls that are not explicitly defined in the extended class, making it easier to work with the MySQLi class without having to override every method. 

class CustomMySQLi extends MySQLi {
    public function __call($method, $args) {
        if (method_exists($this, $method)) {
            return call_user_func_array([$this, $method], $args);
        } else {
            throw new Exception("Method $method does not exist");
        }
    }
}

// Example of using the CustomMySQLi class
$db = new CustomMySQLi('localhost', 'username', 'password', 'database');

// Using a method that is not explicitly defined in CustomMySQLi
$result = $db->query("SELECT * FROM table_name");
