这是一个常见问题，所以让我概括一下并正式化一下一点。

This is a common problem so let me generalize and formalize a little bit.

假设您希望您的Web应用程序支持多种语言，并且具有以下路由要求：

Let's say you want your web app to support multiple languages and you have the following routing requirements:

http://domain.com/language-code/controller-name/action-name

换句话说，您想使用语言代码作为语言环境，并将前一个与默认的Zend模块路由结合起来。

In other words you want to use "language-code" as locale and combine the previous with the default Zend module routing.

假设您还想使用Zend_Translate根据语言环境提供翻译的内容。

Let's assume you also want to use Zend_Translate to provide translated content according to the locale.

这是我使用的一些代码，经常导出到具有类似要求的项目中，我愿意进一步讨论。

Here is some code I use and often "export" into project with similar requirements, I'm open to discuss further.

相关配置项：

resources.frontController.plugins.Language = Plugin_Language
resources.frontController.actionHelperPaths.Controller_Helper = APPLICATION_PATH "/controllers/helpers"


; Locale

resources.locale.default = "en_US"
resources.locale.force = false

; Translate

resources.translate.adapter = "Csv"
resources.translate.data = APPLICATION_PATH "/languages"

resources.translate.locale = "auto"
resources.translate.disableNotices = true
resources.translate.scan = directory



; Routes

resources.router.routes.module.type = Zend_Controller_Router_Route_Module
resources.router.routes.module.abstract = On    

resources.router.routes.language.type = Zend_Controller_Router_Route
resources.router.routes.language.route = ":language"
resources.router.routes.language.reqs.language = "^[a-z]{2}$"
resources.router.routes.language.defaults.language = "en"

resources.router.routes.default.type = Zend_Controller_Router_Route_Chain
resources.router.routes.default.chain = "language,module"


; View

resources.view.helperPath.View_Helper = APPLICATION_PATH "/views/helpers"

这里是注册的插件语言：

Here the registered Plugin language:

class Plugin_Language extends Zend_Controller_Plugin_Abstract {

    public function routeStartup(Zend_Controller_Request_Abstract $request){

        if (substr($request->getRequestUri(), 0, -1) == $request->getBaseUrl()){

            /* Access to the Base Url (no language information) */

            /* Get current locale language (autodetected) */
            $language = Zend_Registry::get("Zend_Locale")->getLanguage();


            /* If requested language isn't available set to the default one */
            if (!Zend_Registry::get('Zend_Translate')->isAvailable($language)){

                Zend_Registry::set(
                    "Zend_Locale", 
                    new Zend_Locale("default")
                );

                $language = Zend_Registry::get("Zend_Locale")->getLanguage();

                Zend_Registry::get("Zend_Translate")->setLocale(
                    Zend_Registry::get('Zend_Locale')
                );
            }


            /* Modifiy Request Uri with Language info from current Locale */
            $request->setRequestUri($request->getRequestUri().$language."/");
            $request->setParam("language", $language);

        }
    }


    public function routeShutdown(Zend_Controller_Request_Abstract $request){

        /* Get language from request param */
        $language = $request->getParam("language");

        /* If requested language isn't available set to the default one */
        if (!Zend_Registry::get('Zend_Translate')->isAvailable($language))
            throw new Zend_Controller_Router_Exception('Translation language is not available', 404);

        /* Set the locale */ 

        Zend_Registry::set(
                "Zend_Locale",
                new Zend_Locale($language)
        );

        /* Set the traslator */ 

        Zend_Registry::get("Zend_Translate")->setLocale(
                Zend_Registry::get("Zend_Locale")
        );


    }

}

动作助手：

class Controller_Helper_Language extends Zend_Controller_Action_Helper_Abstract {

    /**
     * 
     * Get Current language
     * 
     * @return mixed string|null
     */
    public function getCurrent(){

        if (!Zend_Registry::isRegistered("Zend_Locale"))
            return null;

        return Zend_Registry::get("Zend_Locale")->getLanguage();

    }

    /** 
     * 
     * Get translator 
     * 
     * @return mixed Zend_Translate|null
     * 
     */
    public function getTranslator(){

        if (!Zend_Registry::isRegistered("Zend_Translate"))
            return null;

        return Zend_Registry::get("Zend_Translate");

    }

}

视图网址助手（覆盖默认值）。您必须使用正在使用的新路由相应地编写url：

The view url helper (overriding default one). You have to write your urls accordingly with the new routing you are using:

    class View_Helper_Url extends Zend_View_Helper_Url {

    protected function _getCurrentLanguage(){

        return Zend_Controller_Action_HelperBroker::getStaticHelper('Language')
            ->getCurrent();

    }

    public function Url($urlOptions = array(), $name = null, $reset = true, $encode = true){

        $urlOptions = array_merge(
            array(
                "language" => $this->_getCurrentLanguage()
            ),
            $urlOptions
        );

        return parent::url($urlOptions,$name,$reset,$encode);

    }

}

希望此帮助。
