disguise as static content

My personal website (see signature below) is almost entirely built with PHP, based on a rudimentary templating engine that i wrote. With the exception of a few well-defined sections (pictures gallery, blog, etc.) the most of it is static, i.e. it changes very rarely. Some Web applications (including but not limited to search engines) seem to treat differently the static content proper ("true" HTML pages) and pseudo-static content generated by dynamic pages (such as PHP pages that change rarely). I would like to continue to use PHP for my website, but somehow "fool" the Web clients into believing they're seeing "true" static content. Since the content changes rarely (like once every other month), there is no harm in pretending it's "true" static content. I suspect there are quite a few things that can be done to achieve that goal: 1. change extensions to .html even though they're PHP files (i know how to trick Apache into doing that) 2. don't send HTTP headers that indicate dynamic content I don't know how to achieve #2. I also don't know if there are other things to care about in order to totally "disguise" the dynamic nature of the pages. I'm open to suggestions.
