If you're comparing PHP to $lang, true; the gist of SEO is that a page be useful to the visitor. So, whatever you use, make it user-friendly. But if it's a DB driven site, chances are that you'll want to generate some page attributes dynamically, so PHP's good at that.

Or do you suppose there's some steganography going on with these Augusta posters?
