Using directories in URL's instead of long GET query strings

[dummy57]

I've seen this done before and I'm wondering how to implement it. How could I make it so that instead of url's that look like this:

http://www.example.com/test.php?state=Washington&city=Seattle&street=Main

I have url's that look like this:

http://www.example.com/Washington/Seattle/Streets/Main.php

I've read that this directory method is easier on search engines, I just don't have any idea how to implement it. Can anyone give me an idea please?

You would need Apache to make this work. You can search here for .htaccess and mod_rewrite or hit up google.
