Unlike some years back when sites were almost exclusively static, the standard nowadays is to have a feature-rich, dynamic web site. Few people can create this sort of web site completely from scratch though, hence the handiest solution to have a dynamic site is to use a script application. Many web hosting service providers offer script installers that you can use to add this type of an application for any of your domain or subdomains, so you will not need to set up anything manually. The best thing about using an installer tool is the fact that the scripts are ready to use in just a couple of minutes and the copy which will be set up is already with the settings needed for it to run efficiently on the specific hosting server, so you'll not need to modify any script or account settings. In this way you can quickly create one with simply a few mouse clicks even if you have never had a site before.
