.htaccess 重写了一些问题

Question

我当前的 htaccess 文件（重写）有一些问题，如果有人能帮助我解决这个问题，我将不胜感激。

这是我当前的 htaccess 文件：

     Options +FollowSymLinks -MultiViews -indexes
     RewriteEngine On
     RewriteBase /
     # remove .php; use THE_REQUEST to prevent infinite loops
     RewriteCond %{THE_REQUEST} ^GET\ (.*)\.php\ HTTP
     RewriteRule (.*)\.php$ $1 [R=301]
     # remove index
     RewriteRule (.*)/index$ $1/ [R=301]
     # remove slash if not directory
     RewriteCond %{REQUEST_FILENAME} !-d
     RewriteCond %{REQUEST_URI} /$
     RewriteRule (.*)/ $1 [R=301]
     # add .php to access file, but don't redirect
     RewriteCond %{REQUEST_FILENAME}.php -f
     RewriteCond %{REQUEST_URI} !/$
     RewriteRule (.*) $1\.php [L]        
     RewriteCond %{HTTP_HOST} ^domain.com [NC]
     RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
     RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+sections/([^\s]+) [NC]
     RewriteRule ^ %1 [R=301,L]
     RewriteCond %{REQUEST_FILENAME} !-f
     RewriteRule (?!^sections/)^(.*)$ /sections/$1 [L,NC]

在我的 public_html 文件夹中，我有一个名为sections 的子文件夹，它本身包含几个其他子文件夹。我想要实现的是使用我上面发布的配置实际隐藏 /sections/ 文件夹，该文件夹在一定程度上起作用，但是我仍然遇到一些问题。

如果我要打开 www.mydomain.com/sections/file 它会成功重定向到 www.mydomain.com/file - 这已经很好了，但是如果我尝试添加 .php 扩展名（仅用于测试目的）重定向有效（部分文件夹被跳过），但是文件扩展名没有被修剪（我仍然看到 .php）应该被删除并且我看到一个页面文本 Moved Permanently - 文档已移至此处...

在我当前的 .htaccess 文件中我可以做/修改什么或不正确的事情吗？一些专家的建议将不胜感激。

非常感谢！

完成.htaccess：

 Options +FollowSymLinks -MultiViews -indexes
 RewriteEngine On
 RewriteBase /

 RewriteCond %{HTTP_HOST} ^domain\.com$ [NC]
 RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R=301]

 RewriteCond %{THE_REQUEST} \s/+sections/(.+?)(?:\.php)?[/?\s] [NC]
 RewriteRule ^ %1 [R=301,L]

 # remove index
 RewriteCond %{THE_REQUEST} /index(\.php)?[\s?/] [NC]
 RewriteRule ^(.*?)index(/|$) /$1 [L,R=301,NC,NE]

 # remove .php; use THE_REQUEST to prevent infinite loops
 RewriteCond %{THE_REQUEST} ^GET\ (.*)\.php\ HTTP
 RewriteRule (.*)\.php$ $1 [L,R=301]

 # remove index
 RewriteRule (.*)/index$ $1/ [R=302]
 # remove slash if not directory
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteCond %{REQUEST_URI} /$
 RewriteRule (.*)/ $1 [R=301,L]

 # add .php to access file, but don't redirect
 RewriteCond %{REQUEST_FILENAME}.php -f
 RewriteCond %{REQUEST_URI} !/$
 RewriteRule (.*) $1.php [L]

 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteRule (?!^sections/)^(.+)$ /sections/$1 [L,NC]
