I know how to make a PHP site of the form '/index.php?page=person&name=jeffjohnson'

What I'm wondering is, how do you do a site where the fact that it's coming from a script is hidden, i.e. the above address would instead be '/person/jeffjohnson/'?

Thanks,
Rich

Forgot to mention, it's using Apache. (It's in the subject line, but someone could miss that.)
