     * You can add parameters to a translation message that will be substituted with the corresponding value after

     * ```php
     * $username = 'Alexander';
     * echo \Yii::t('app', 'Hello, {username}!', ['username' => $username]);
     * ```
     *
     * Further formatting of message parameters is supported using the [PHP intl extensions](http://www.php.net/manual/en/intro.intl.php)
     * message formatter. See [[\yii\i18n\I18N::translate()]] for more details.
     *
     * @param string $category the message category.
     * @param string $message the message to be translated.
     * @param array $params the parameters that will be used to replace the corresponding placeholders in the message.
     * @param string $language the language code (e.g. `en-US`, `en`). If this is null, the current
     * [[\yii\base\Application::language|application language]] will be used.
     *
     * @return string the translated message.
