html to php

[cocoy]

site's whole content is html and planning to change it to php. what is the best redirection method without losing any traffic and following google's guidelines?

aside from 301 redirection, are there any other ways? should I delete the html files?

There are several ways to do it. If your server supports it, you can execute php code in a html file with a command like the following in the .htaccess file

RemoveHandler .html .htm
AddType application/x-httpd-php .php .html

Another way would be a rewriterule to change the php files to htm files.

RewriteRule (.*)\.htm$ $1\.php

check the syntax as it may not work on all servers.
