    'components' => [
        'lang' => [

                'html' => [
                    0 => 'en',
                    1 => 'zh-Hant',
                    2 => 'zh-Hans',
                ],
            ],
            // 'storage' => 'session',
            // 'storageKey' => 'language',
        ],
        ...
property Type Default Description
languages array As example Supported language list
maps array As example Customized language map
storage string 'session' Storage carrier: 'session' or 'cookie'
storageKey string 'language' Storage carrier Key

Bootstrap

You could add the language component into bootstrap for keeping the language storage work such as Seesion and Cookie.

// `lang` component for example
return [
    'bootstrap' => ['lang'], 
    ...

USAGE

get()

Get Current Language

public string get($map=null)

Example:

echo \Yii::$app->lang->get();  // en-US

You could get from map by giving map key as first argument:

echo \Yii::$app->lang->get('html');  // en

set()

Set Current Language synchronised to \Yii::$app->language

public boolean set($language)

Example:

\Yii::$app->lang->set('zh-TW');

getByMap()

Get customized language value from $map

public string getByMap($mapKey)

Example:

If you have to echo HTML language value by current language:

echo \Yii::$app->lang->getByMap('html');  // en

setByMap()

Set by using customized language value from $map

public boolean setByMap($mapKey, $mapValue)

Example:

If you have to set current language by inputting a HTML language value:

$this->setByMap('html', 'zh-Hant');

isFirstCome()

First time coming check, which has no StorageRecord

Inverse alias with hasStorageRecord()

public boolean isFirstCome()

Example:

if (Yii::$app->lang->isFirstCome()) {
    // Detetmine user ip to set current language
} 
else if (Yii::$app->lang->hasStorageRecord()) {
    // Means !(Yii::$app->lang->isFirstCome())
}

IMPLEMENTATION

Controller for Changing Language

You could add a controller or action for changing language like /language?language=zh-TW:

<?php

namespace app\controllers;

use Yii;
use yii\web\Controller;

/**
 * The Controller for Language converting
 */
class LanguageController extends Controller
{
    public function actionIndex($language='')
    {
        $result = Yii::$app->lang->set($language);
        
        return $this->redirect(Yii::$app->request->referrer ?: Yii::$app->homeUrl);
    }
}

BeforeAction for globally changing language

You could globally set language by handling language setting in the bootstrap of application.

For example, get GET parameter to set language in on beforeAction function:

return [
    'on beforeAction' => function ($event) {
        // Always fetch language from get-parameter
        $lang = \Yii::$app->request->get('lang');
        // Set to given language with get-parameter
        if ($lang) {
            $result = \Yii::$app->lang->set($lang);
        }
    },
    ...
]

After that, by giving lang param from any url like /post/my-article?lang=zh-TW would change language.
