MediaWiki

Head up! Wikimedia is not an application that uses a specific interface. Instead, it consists of a PHP program program and a text document set up in various programming languages ??such as JavaScript, HTML, and PHP.

The way to edit Wikipedia's website templates is based on the Wikipedia philosophy: You can modify the contents of a user page, upload images, etc. It works because Wikimedia technology lets you retrieve data from users' unwanted changes

To install templates, change, or try the website, you must have the following applications: DynaFair or other HTML editor to modify the page or source code appearance; Examines an Apache server and MySQL database site; And PHP version 4.3 or higher.

It does not need to know much like SQL, HTML or CSS to create a website, although at least it is helpful to know a PHP.
