php-如何更改htaccess以对主页和帖子页面进行分类

I'm working on a php website . I heard we can change the htaccess to identify whether it is home page, post page or search page.

Currently I'm using the below details.

RewriteCond %{REQUEST_URI} ^/index\.(html|php)
RewriteRule ^(.*) /home.php

Where the Index.php gets the url and identifies whether it is home page , search page or url page.

Is there an easy way to do it?

Thanks a lot for your suggestions .
