How do I make a rewrite rule in php?

Question

RewriteEngine on
Rewriterule ^(.*).htm $1.php

This works fine when i try to access every php page

But how could i make it RewriteRule

Answer 1

RewriteRule ^/about/$ /about.php

Answer 2

Alternatively to Jan's answer:

RewriteRule ^/about/?$ /about.php

will rewrite it whether they remember the final / or not.

Answer 3

If you want to use the rule in a .htaccess file, you need to remove the local path prefix from the pattern as it is removed before testing the pattern. In case of the root directory that is the /. So try this:

RewriteRule ^somepage/$ /somepage.php

And for arbitrary path segments:

RewriteRule ^([^/]+)/$ /$1.php
