Some of you have sites that are written in .html and do not want to change the extension of every page but would like the ability to run PHP on a page that ends in .html

This can be achieved on systems that run PHP as a CGI (like ours) by adding the following directive to your .htaccess file:

AddHandler application/x-httpd-php .html
If you have a dedicated server and still run PHP as a module then your .htaccess would be like:

AddType application/x-httpd-php .html
All GlowHost shared and reseller servers use PHP CGI.
