Create .htaccess file in root folder, i.e advanced/.htaccess and write below code.

Options +FollowSymlinksRewriteEngine On# deal with admin firstRewriteCond %{REQUEST_URI} ^/(admin) <------RewriteRule ^admin/assets/(.*)$ backend/web/assets/$1 [L]RewriteRule ^admin/CSS/(.*)$ backend/web/css/$1 [L]RewriteCond %{REQUEST_URI} !^/backend/web/(assets|css)/  <------RewriteCond %{REQUEST_URI} ^/(admin)  <------RewriteRule ^.*$ backend/web/index.php [L]RewriteCond %{REQUEST_URI} ^/(assets|css)  <------RewriteRule ^assets/(.*)$ frontend/web/assets/$1 [L]RewriteRule ^css/(.*)$ frontend/web/css/$1 [L]RewriteCond %{REQUEST_URI} !^/(frontend|backend)/web/(assets|css)/  <------RewriteCond %{REQUEST_URI} !index.phpRewriteCond %{REQUEST_FILENAME} !-f [OR]RewriteCond %{REQUEST_FILENAME} !-dRewriteRule ^.*$ frontend/web/index.php

Note : if you are trying in local server then replace ^/ with ^/PRoject_name/ where you see arrow sign. Remove those arrow sign <------ after setup is done.

Now create a components/Request.php file in common directory and write below code in this file.

namespace common/components;class Request extends /yii/web/Request {    public $web;    public $adminUrl;    public function getBaseUrl(){        return str_replace($this->web, "", parent::getBaseUrl()) . $this->adminUrl;    }    /*        If you don't have this function, the admin site will 404 if you leave off         the trailing slash.        E.g.:        Wouldn't work:        site.com/admin        Would work:        site.com/admin/        Using this function, both will work.    */    public function resolvePathInfo(){        if($this->getUrl() === $this->adminUrl){            return "";        }else{            return parent::resolvePathInfo();        }    }}

Installing component. Write below code in frontend/config/main.php and backend/config/main.phpfiles respectively.

//frontend, under components array'request'=>[    'class' => 'common/components/Request',    'web'=> '/frontend/web'],'urlManager' => [        'enablePrettyUrl' => true,        'showScr
 create .htaccess file in web directory
RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /index.php?/$1 [L]
Note: make sure you have enabled your mod rewrite in apache
Thats it! You can try your project with 
www.project.com/admin, www.project.com
in local server
localhost/project_name/admin, localhost/project_name
以上是高級版的Advanced配置方法，基礎版的不需要這樣配置。
 Advanced和 basic 最大的區別就是分離了前后臺 分別是 backend目錄和frontend目錄 這兩個目錄實際相對于 basic 來說其實就是兩個Yii應用 他們公用的比如Model部分都存放在Common目錄 這種高級應用適用于比較復雜大型的項目用于徹底分離開前后臺業務邏輯 因此訪問前后臺就相當于訪問兩個不同的應用
因此在配置Vhost webroot 目錄的時候 假設域名為 www.xxx.com 那么 www.xxx.com指向前臺目錄 /frontend/web/
配置二級域名root.xxx.com 指向/backend/web/
    對于剛接觸Yii2的筒子建議先從basic入手
