PHP (Hypertext Preprocessor) is a server-side scripting language used primarily for web development.
It was created by Rasmus Lerdorf in 1994 as a set of CGI scripts in the C programming language to track visitors to his personal website.
He added more functionality to the language and released it as PHP/FI (Personal Home Page/Forms Interpreter) in 1995.
Andi Gutmans and Zeev Suraski rewrote the language from scratch in 1997, and the new version was released as PHP 3.0.
PHP has become one of the most widely used programming languages on the web, powering popular websites such as Facebook, Wikipedia, and WordPress.
PHP is an open-source language, meaning anyone can use and contribute to its development.
It has a large community of developers and offers compatibility with a wide range of web servers and operating systems.
PHP is versatile and not only used for web development but also for command-line scripting and desktop application development.
It has strong integration with popular databases like MySQL, Oracle, and PostgreSQL, and has several popular frameworks that make web development faster and more efficient.
