Yii2 language pack settings

The Yii2 framework is famous for its performance and has many users. Sometimes our projects may require multi-language support, so how to configure the language pack of Yii2? Let’s set up the language pack of Yii2 today.

The multi-language version of yii2 is almost similar to yii1

1. Set the default language: Add: 'language'=>'zh-CN'

# to the mail.php configuration file ##2. Multi-language switching

<a href="<?php echo Yii::$app->urlManager->createUrl([&#39;/ebay/user/language&#39;,&#39;lang&#39;=>&#39;zh-CN&#39;]);?>">中文</a>  
<a href="<?php echo Yii::$app->urlManager->createUrl([&#39;/ebay/user/language&#39;,&#39;lang&#39;=>&#39;en&#39;]);?>">英文</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']);  
}

Multi-language file messages path

Add a sentence to the entry file web/index.php

Be sure to add it in the middle

This way you can switch the language

2. The second method

We can also initialize, but this is troublesome. Each controller needs to write an init function. The main thing is to assign a value to

Yii::$app->language
