I want to move my site to a php-based file system. Right now, all of my archive files are *.html and I want to change that to *.php without screwing up the linking on search engines and other sites.

Does anyone know how to redirect html to php with an htaccess file? If I try wildcards *.html or any other changes, I get a 500 error.

Does something like this work?

Thanks! That works.

You can run php in .html files by adding this to your htaccess:
AddType application/x-httpd-php .html .php

Then you don't have to change the extensions at all.

Ya know, it's funny - that was the first thing I went looking for - the thread where you posted that. Then I thought, oh, that's not what he/she wants!

Duh to me!!

I tried that first bmk and it doesn't work with my host.  But thanks for all of the help.
