The landscape of PHP is always evolving. Right now, a staggering 82% of the Web runs on PHP. At the same time, the use of content management systems and pre-built application frameworks has skyrocketed as well. For example, 22% of all websites in the world are built on WordPress. Other frameworks – such as Joomla!, Drupal, and Magento – trail not far behind. More often, while PHP is the actual programming language powering websites, it isn’t ‘raw’ PHP doing it, but one of these frameworks instead.
