yii2 multi-language settings

yii2 multi-language settings

1. Set the default language: add: 'language'=>'zh_cn' in the mail.php configuration file

2. Multi-language switching
html code:

<a href="<?php echo Yii::$app->urlManager->createUrl(['/test/language','lang'=>'zh_cn']);?>">中文</a>  
<a href="<?php echo Yii::$app->urlManager->createUrl(['/test/language','lang'=>'en']);?>">English</a>  

controller code:

//语言切换 
public function actionLanguage(){       
    $language=  \Yii::$app->request->get('lang');  
    if(isset($language)){  
        \Yii::$app->session['language']=$language;  
    }  
    //切换完语言哪来的返回到哪里
    $this->goBack(\Yii::$app->request->headers['Referer']);  
}  

3. Multi-language file messages path

4. Modify the entry file web/index.php:

(new yiiwebApplication($config))->run();
Changed to:
$ application = new yiiwebApplication($config);
$application -> language = isset(Yii::$app->session['language']) ? Yii::$app->session['language'] : 'zh_cn';
$application -> run();

This way you can switch languages ​​
