Its pretty easy to create a flash message class with PHP sessions.

class FlashMessage {

    public static function render() {
        if (!isset($_SESSION['messages'])) {
            return null;
        }
        $messages = $_SESSION['messages'];
        unset($_SESSION['messages']);
        return implode('<br/>', $messages);
    }

    public static function add($message) {
        if (!isset($_SESSION['messages'])) {
            $_SESSION['messages'] = array();
        }
        $_SESSION['messages'][] = $message;
    }

}

Make sure you are calling session_start() first. Then you can add messages using FlashMessage::add('...');

Then if you redirect, you can render the messages next time you render a page echo FlashMessage::render(). Which will also clear the messages.
