Also, give XAMPP a Google. It contains everything you need to get up and running with PHP. Make sure you read all of the instructions, though.
http://www.php.net Download the installer and run it. If you want to create PHP based websites then install Apache first from http://httpd.apache.org/ Get the latest 2.2.x version. Apache is the A in XAMPP and WAMP If you're just learning how to program then getting MySQL (the M in XAMPP and WAMP) is probably a little much at this point. I personally prefer TextPad for coding PHP with. If you want a nice IDE to get things like code completion etc, then you can go with http://www.phpeclipse.com/
Definitely go with a WAMP. It's easy to install and you can even load the whole thing on to a usb key for portability. Search google for MoWeS Portable, that should contain everything you need to be up and running in a matter of minutes.
