Unlike some years back when sites were almost exclusively static, the standard nowadays is to have a feature-rich, dynamic website. Not many people can build this sort of website from scratch though, therefore the most convenient solution to have a dynamic website is to use a script application. Lots of web hosting service providers offer script installers which can be used to add such an app for each of your domain or subdomains, so you will not need to set up anything manually. The best thing about using an installer tool would be that the scripts are ready to use within a few minutes and the copy which will be installed is already with the settings needed for it to run properly on the specific hosting web server, so you'll not need to adjust any script or account settings. This way you can quickly create one with just a couple of clicks even when you have never had an Internet site before.
