Php and SEO

Hi

Just wanting a bit of advice and reassurance.
We are in the middle of designing a large business directory in php.
How does Php perform in the search engines, good listings are critical for the site we are developing so are we wasting our time using php?

I've heard you can mod-rewrite your pages, so that your variables comes across as cat_11_111.htm instead of cat.php?sid=11?sid2=111

does anyone have any experience of this and have any advice to offer?

Thanks in advance
