Dynamic websites are becoming progressively more popular due to their flexible and easy content management. The main difference between this type of websites and the standard HTML static websites is the database system running on the back end of each dynamic site.

Dynamic sites do not have preset content pages, but rather work with a number of templates, that are pulled out and populated with content in real time as the user navigates from one section of the website to another. All content for the website resides in the back end database and is only pulled out and displayed if someone is interested in viewing the respective section.

Because the content is stored in a database it is very easy to review and update. As a result dynamic websites are easier to maintain and the agency administrators can update the website themselves through special administrative interface forms. Knowledge of HTML is not a prerequisite in this case.

In contrast to a static website, a dynamic website is one whose content is regenerated every time a user visits or reloads the site.

There are a variety of languages available to make a dynamic website but in this course, we will focus on PHP. PHP stands for PHP: Hypertext Preprocessor. This confuses many people because the first word of the acronym is the acronym. This type of acronym is called a recursive acronym.
