Rocket City Sitters
You can view the code without a web server, by running straight php:
php.exe index.php > index.html
... do this for each file
Then open e.g. index.html in your browser.
LAMP / WAMP
For a more holistic solution, I would suggest to install either:
LAMP - Linux, Apache, MySQL, PHP
WAMP - Windows, Apache, MySQL, PHP
on your local machine and use that to serve up the php webpages.
