Question

I have revamped a website and now the URLs are different in their format.

Formerly a page was www.example.com/about.

Now it is www.example.com/about.php

How can I write a redirect rule so that when a user clicks an old URL (from search engines or whathaveyou) ‘www.example.com/about’ it receives a 301 redirection over to www.example.com/about.php?

Answer 1

Try this:

RewriteEngine on
RewriteRule ^(.*) /$1.php [R=301,L]

Updated Answer:
Sorry, this was not as straightofeward as I thought.

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} -f [NC,OR]
RewriteCond %{REQUEST_FILENAME} -d [NC] 
RewriteRule (.+?)(\.[^.]*$|$)$ $1.php

It should be in the root web directory where your URL maps to, sounds like public_html.
