htaccess redirect old index.php with extensions to new url

Question

I am having some trouble redirecting these links properly through htaccess.

Website use to be dynamic, and is now static.

This page does not exist anymore, but there are still links out there that reference the page through these url's, so I need them redirected.

http://www.example.com/?en=about

and

http://www.example.com/index.php/?en=about

They should be redirected to a new static html page recently created.

What is the best way to go about this through htacess? I've tried some rewrites, but not working. Any help would be appreciated - thanks

Answer 1

I suggested that the file name matches the value en

 RewriteEngine on

RewriteCond %{QUERY_STRING} ^en=([^&]+)
RewriteRule ^(index.php/|)$ /%1.html? [R,L]

If only one page - about-us, then code below

RewriteEngine on

RewriteCond %{QUERY_STRING} ^en=about
RewriteRule ^(index.php/|)$ /about-us.html? [R,L]

Answer 2

You should be able to 301 for permanent redirect:

Redirect 301 /old.php /new.php

So in your case you would want something like:

Redirect 301 /index.php/?en=about /about.php
