访客用户和登录用户的两种不同布局 - Yii2 - Two different layouts for Guest User & Logged in User- Yii2

以前，我有main.php，其中声明了页眉和页脚。这没关系。现在，我正在为 Guest User 和 Registered User 寻找 2 种不同的布局。其中Registered User和Admin将具有不同的页眉和页脚。

我正在使用 Yii2 基本应用程序。我在文件夹中创建了 GuestUser.php & RegisterUser.php views/layouts/。

访客用户表示用户尚未登录应用程序。并且，注册用户表示用户已登录应用程序。

现在，我的目录结构是这样的。

views
    ->layouts
        ->main.php
        ->GuestUser.php
        ->RegisteredUser.php
    ->site

现在，我如何在我的应用程序中使用 GuestUser.php & RegisterUser.php。至于现在，默认情况下，应用程序是主要的.php。我该如何控制？

我试过了

主.php

<?php if(Yii::$app->user->isGuest){?>
    <?php $this->beginContent('@app/views/layouts/GuestUser.php'); ?>
            <?=$content;?>
    <?php $this->endContent();?>
<?php } else {?>
    <?php $this->beginContent('@app/views/layouts/RegisteredUser.php'); ?>
            <?=$content;?>
    <?php $this->endContent();?>
<?}?>

任何帮助/提示/建议都是可观的。请帮忙。

为整个应用程序实现此目的的一种方法可能是设置使用应用程序事件处理程序并配置布局文件：

//in web.php
$config = [
    ....
    'on beforeRequest' => function ($event) {
        Yii::$app->layout = Yii::$app->user->isGuest ? 
            '@app/views/layouts/GuestUser.php' :      // or just use 'GuestUser' and 
            '@app/views/layouts/RegisteredUser.php';  // 'RegisteredUser' since the path 
                                                      // and the extension are used by
                                                      // default
    },
    ....
];

如果只想在单个控制器中执行此操作，则可以在控制器中使用布局。只需使用控制器中的文件名（不带 .php）重写此成员即可。
