Unlike some years ago when websites were almost exclusively static, the standard nowadays is to have a feature-rich, dynamic website. Not many people can build such a site completely from scratch though, so the handiest solution to have a dynamic website is to use a script application. A lot of website hosting companies offer script installers you can use to add this sort of an application for each of your domain name or subdomains, so you will not have to add anything manually. The main advantage of using an installer tool is that the scripts are available to use in just a few minutes and the copy that will be installed is already with the settings needed for it to run adequately on the particular hosting web server, so you will not need to adjust any script or account settings. That way you can effortlessly create one with only a few mouse clicks even if you have never had an Internet site before.
