Enhance Your Site with PHP Includes
An external style sheet allows all of a site’s styles to be controlled from one point—which makes for very efficient page layout and design.
“PHP includes” can be used in a similar way to external style sheets, in that elements appearing on multiple pages can be controlled from one location. For example, it is common to have a menu on every page of a website. If you want to update that menu—such as adding a new menu item—it will be a nightmare to do this if you have to open every page on your site to alter each instance of that menu.
