Even better, try setting up WAMP
Ill explain: its a package of programs to run a webserver.
Windows
Apache
MySQL
PHP
You can setup wamp and have a running Apache (webserver) with PHP support and
when you get further in developing even a MySQL database!
You only need to install it, configure it, and put all your files in the WWW folder.
then visit 127.0.0.1 in your browser and you got a fully working website and you can test your PHP pages there. Remember this is only usefull for testing, or you want to keep your computer online 24/7 but i recommend a webhost.
