It doesn't matter to them.
However with pages with a query string they know that you can easily write a script that produces millions of pages, and they don't want to be caught up indexing them.
So while they have never had problems indexing pages with query strings (a query string is anything that follows a question mark in a URL), they will sometimes limit the number of said pages that they will index from a particular domain. Likely one of the things they look at is if a page is linked to from a "static" page, and if it is then they will likely index it. PR is also probably a factor.
One thing you can do is create search engine friendly URLs. Not only will these make your PHP pages look static, but they will also hide which server side technology you are using (which can boost security and make it easier to change technologies in the future) and they are also people friendly.
I wrote an article on doing this:
