来自外部文件夹的Joomla

Question

我需要从外部文件夹加载网站。 现在我们在主文件夹（public_html/web）的public_html/index.php子文件夹中有一个WordPress，我们的index.php具有：

<?php
/**
* Front to the WordPress application. This file doesn't do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require('./web/wp-blog-header.php');

让网站保持域www.mydomain.com在子文件夹中的加载而无需放置www.mydomain.com/web，现在我们需要更改该文件以加载位于public_html/web2上的Joomla网站
