My intention was to use .htaccess to rewrite all urls with an extension of .html to .php, not to parse .html as php. In other words, I've inserted my php tags into my existing html files and renamed them with the .php extension. My desire is to automatically direct users who are looking for the original html files to the new php files.
Is this possible? I thought that the Apache RewriteEngine directive would accomplish this, but I may be entirely wrong.
I suppose I could change the extensions back to .html and use your suggestion to parse them all as php, but I have other html files on the site that don't contain any php tags and don't need to be parsed as php.
