.htaccess file and URL rewrite rule in php

Sometimes you need to redirect some URL and/or page on your site to another one.    
using the “Redirect” directive:    
   
Redirect /folder http://www.example.com/newfolder      
   
Another useful directive is the RedirectMatch    
   
RedirectMatch "\.html$" http://www.example.com/index.php
