WordPress is a free and open-source content management system (CMS) based on PHP and MySQL.
WordPress is a free and open-source content management system (CMS) based on PHP and MySQL. To function, WordPress has to be installed on a web server, which would either be part of an Internet hosting service or a network host in its own right.
An example of the first scenario may be a service like WordPress.com, and the second case could be a computer running the software package WordPress.org. A local computer may be used for single-user testing and learning purposes.
Features include a plugin architecture and a template system. WordPress is used by 30.6% of the top 10 million websites as of April 2018. As such, WordPress is the most popular website management or blogging system in use on the Web, supporting more than 60 million websites. WordPress has also been used for other application domains such as pervasive display systems (PDS).
Founded in 2003
WordPress has a web template system using a template processor. Its architecture is a front controller, routing all requests for non-static URIs to a single PHP file which parses the URI and identifies the target page. This allows support for more human-readable permalinks.
1. WordPress Themes
WordPress users may install and switch among different themes. Themes allow users to change the look and functionality of a WordPress website without altering the core code or site content.
Every WordPress website requires at least one theme to be present and every theme should be designed using WordPress standards with structured PHP, valid HTML (HyperText Markup Language), and Cascading Style Sheets (CSS). Themes may be directly installed using the WordPress “Appearance” administration tool in the dashboard, or theme folders may be copied directly into the themes directory, for example via FTP.
WordPress themes are generally classified into two categories: free and premium. Many free themes are listed in the WordPress theme directory, and premium themes are available for purchase from marketplaces and individual WordPress developers.
2. WordPress Plugins
WordPress’ plugin architecture allows users to extend the features and functionality of a website or blog. WordPress has over 50,316 plugins available, each of which offers custom functions and features enabling users to tailor their sites to their specific needs.
