Do a view source from your browser on one of your php pages. That is what the spiders see. It's a html web page, exactly like any other web page, so can be optimised exactly like a static html page.

PHP runs on the server to generate the html code, and you have complete control of the html in exactly the same way as when you write a static html page in your editor.

The only potential problem I can think of is where php is set to append a sessionid onto the end of your urls. If you're not doing this, spiders/search engines will have no problems indexing your php pages.
