What can PHP do for you? PHP can create dynamic applications that can be delivered over the Web. In comparison, HTML can only create static content because the Web browser interprets the page when it is requested; the server doesn’t do anything but send the page to the browser. But when a PHP page is requested on the server, the server itself processes the code that is in the proper delimiters and sends the final results to the Web browser. This allows you to pull different content into the page each time it is requested. This is very handy for you because now you can create an interactive game that is updated from user input.
