Twig. Как подставить переменную в текст из базы?

public function phrase($phrase, $language = 0) {
        $defaultLanguage = $this->option('board_language');
        if ($language == 0) { $language = $defaultLanguage; }
        $this->db = new DataBase;
        $data = $this->db->prepareFetchAssoc('SELECT `phrase_text` FROM `fox_language` WHERE phrase_code = ? AND language_code = ?', array($phrase, $language));
        if ($data['phrase_text']) {
            return $data['phrase_text'];
        } else {
            return $phrase;
        }
    }

$loader = new Twig_Loader_Array([
    'index.html' => phrase('Hello {{ name }}!', 123),
    'page.html' => phrase('Page {{ name }}! {{ content }}', 123),
]);
$twig = new Twig_Environment($loader);
echo $twig->render('index.html', ['name' => 'Fabien']);
