我在 /dashboard/.htaccess [dashboard 实际上是一个文件夹] 中放置了这个重写规则：
RewriteRule ^([^/]*)$ index.php?mode=$1 [L]
我的结构是 index.php?mode=support，尽管 $_SERVER['QUERY_STRING'] 输出如下：
mode=index.php
Example: site.com/dashboard/index.php?mode=support should be site.com/dashboard/support
那么，我怎样才能让它解析参数值，而不是文件本身。
在对正则表达式进行更多研究的同时设法解决了这个问题。
RewriteRule ^([a-z]+)$ index.php?mode=$1 [L,QSA]
Thi 解决了我的问题，首选加号而不是星号，因为它告诉引擎重复它零次或多次。（当我在 index.php 时，查询字符串根据需要为空）
Your rule is matching anything that starts with not a slash and doesnt contain a slash anywhere when your actual path is
/dashboard/support
to get the folder you actually want you need a base on there like this
RewriteBase /dashboard/
If that is placed above the rule, Then your redirect should be ok
