如何删除URL中的参数.htaccess [关闭]

I have a very big problem, I'am using to CLEAN URL this link.We are make a small CMS system for PHP and make a new web site.

Problem is, my customer.

My customer don't want these link style :

www.example.com/page/about-us
www.example.com/page/contact-us
www.example.com/anotherpage/lorem-ipsum-dolar

How to remove or hide /page, /anotherpage using .htaccess ?

My .htaccess file is ;

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^ index.php [L]
</IfModule>

You can probably use .htaccess Rewrite rule to solve this issue:

RewriteRule url-wanted$ actual-url [L,QSA]

Example:

RewriteRule www.example.com/about-us$ www.example.com/page/about-us [L,QSA]
