The advantage of this approach is that it introduces a separation
between business logic and presentation. If you intermingle these two
things then it makes life harder than necessary later down the line
when changes have to be made to either thing. You can even delegate
the presentation side of things to a web designer who doesn't know a
lot of PHP but can turn out really nice looking pages should you
wish :)
