yii 2.0语言配置

在config main.PHP 添加
// 语言
‘i18n’ => [
‘translations’ => [
‘common*’ => [
‘class’ => ‘yii\i18n\PHPMessageSource’,
‘fileMap’ => [
‘common’ => ‘common.PHP’,
],
],
‘order-transfer*’ => [
‘class’ => ‘yii\i18n\PHPMessageSource’,
‘fileMap’ => [
‘common’ => ‘order-transfer.PHP’,
],
],

        ],
    ],

然后配置语言切换
/**
* displays homepage.
*
* @return string
*/
public function actionMessages()
{
$language = Yii::$language=Yii::app->request->get(‘zh’);

    $session = Yii::$app->session;
    $session->open();
    if(isset($language)){
    Yii::$app->session['language'] = $language;
    }
    $this->redirect(Yii::$app->request->headers['Referer']);
}
