Checking for a web server (Windows)
To develop and test dynamic web pages, you need a web server. A web server is software that serves web pages in response to requests from web browsers.
Make sure Microsoft IIS is installed and running on your hard disk or on a remote Windows computer. A quick way to check whether IIS is installed on a computer is to look at the folder structure to see whether it contains a C:\Inetpub or D:\Inetpub folder. IIS create this folder during installation.
If IIS is not installed, install it now. For instructions, see Installing a Web Server.
After installing the web server, install the application server. (See Installing a PHP application server (Windows).)
