What is PHP, and How Does It Work?

PHP (short for Personal Home Page) is a server-side programming language widely used in web development. Created by Rasmus Lerdorf in 1994, PHP has evolved into a robust tool for building dynamic web pages and interactive web applications.

PHP operates on a server-side processing model, where PHP code is executed on the server before the results are sent to the user’s browser. PHP code can be embedded within HTML or written as separate files and is interpreted by a web server running a PHP interpreter.

What Does PHP Do?

PHP primarily handles client requests and generates dynamic content for web browsers. It enables database interaction, form processing, session management, file manipulation, and other tasks required to build dynamic websites and complex web applications.

PHP in WordPress

WordPress, a popular content management system (CMS), relies heavily on PHP for its development and functionality. Written in PHP, WordPress uses a wide range of PHP functions and classes to process requests and render web pages.

PHP in WordPress empowers users to customize themes and plugins, extending WordPress’s functionality. It allows the creation of dynamic websites, database management, interactive forms, and more, tailoring WordPress to meet specific needs.
