How to Use Mirror Sites to Create a Multilingual Typecho Site

While attempting to use Typecho to create a bilingual blog, I encountered a problem: I wanted the blog to support both Chinese and English languages. However, after some searching, I couldn't find a method to directly implement this function. Therefore, I learned PHP on the fly and tried using the mirror site mode. The blog site is a Chinese site, and the enblog site is an English site. Users can switch between them in the sidebar. This is a crude method, but it's a convenient one for someone like me who isn't very technically proficient. I'm sharing my code here in the hope that it will inspire others to further optimize it.

Here is the original Sidebar.php, used for the Default template.

<?php if (!defined('__TYPECHO_ROOT_DIR__')) exit; ?>
<div class="col-mb-12 col-offset-1 col-3 kit-hidden-tb" id="secondary" role="complementary">
    <?php if (!empty($this->options->sidebarBlock) && in_array('ShowRecentPosts', $this->options->sidebarBlock)): ?>
        <section class="widget">
            <h3 class="widget-title"><?php _e('最新文章'); ?></h3>
            <ul class="widget-list">
                <?php \Widget\Contents\Post\Recent::alloc()
                    ->parse('<li><a href="{permalink}">{title}</a></li>'); ?>
            </ul>
        </section>
    <?php endif; ?>

    <?php if (!empty($this->options->sidebarBlock) && in_array('ShowRecentComments', $this->options->sidebarBlock)): ?>
        <section class="widget">
            <h3 class="widget-title"><?php _e('最近回复'); ?></h3>
            <ul class="widget-list">
                <?php \Widget\Comments\Recent::alloc()->to($comments); ?>
                <?php while ($comments->next()): ?>
                    <li>
                        <a href="<?php $comments->permalink(); ?>"><?php $comments->author(false); ?></a>: <?php $comments->excerpt(35, '...'); ?>
                    </li>
                <?php endwhile; ?>
            </ul>
        </section>
    <?php endif; ?>

    <?php if (!empty($this->options->sidebarBlock) && in_array('ShowCategory', $this->options->sidebarBlock)): ?>
        <section class="widget">
            <h3 class="widget-title"><?php _e('分类'); ?></h3>
            <?php \Widget\Metas\Category\Rows::alloc()->listCategories('wrapClass=widget-list'); ?>
        </section>
    <?php endif; ?>

    <?php if (!empty($this->options->sidebarBlock) && in_array('ShowArchive', $this->options->sidebarBlock)): ?>
        <section class="widget">
            <h3 class="widget-title"><?php _e('归档'); ?></h3>
            <ul class="widget-list">
                <?php \Widget\Contents\Post\Date::alloc('type=month&format=F Y')
                    ->parse('<li><a href="{permalink}">{date}</a></li>'); ?>
            </ul>
        </section>
    <?php endif; ?>

    <?php if (!empty($this->options->sidebarBlock) && in_array('ShowOther', $this->options->sidebarBlock)): ?>
        <section class="widget">
            <h3 class="widget-title"><?php _e('其它'); ?></h3>
            <ul class="widget-list">
                <?php if ($this->user->hasLogin()): ?>
                    <li class="last"><a href="<?php $this->options->adminUrl(); ?>"><?php _e('进入后台'); ?>
                            (<?php $this->user->screenName(); ?>)</a></li>
                    <li><a href="<?php $this->options->logoutUrl(); ?>"><?php _e('退出'); ?></a></li>
                <?php else: ?>
                    <li class="last"><a href="<?php $this->options->adminUrl('login.php'); ?>"><?php _e('登录'); ?></a>
                    </li>
                <?php endif; ?>
                <li><a href="<?php $this->options->feedUrl(); ?>"><?php _e('文章 RSS'); ?></a></li>
            </ul>
        </section>
    <?php endif; ?>

</div><!-- end #sidebar -->

这是现在的Sidebar.php

<?php if (!defined('__TYPECHO_ROOT_DIR__')) exit; ?>
