PHP - The Popular General-Purpose Scripting Language
Introduction
PHP, which stands for "Hypertext Preprocessor," is a widely-used open-source server-side scripting language. It was initially created in 1994 by Rasmus Lerdorf and has evolved significantly over the years. PHP remains one of the most popular languages for web development due to its simplicity, flexibility, and extensive community support.
A Brief History of PHP
PHP began as a set of Common Gateway Interface (CGI) binaries written in C by Rasmus Lerdorf to track visits to his online resume. Initially called "Personal Home Page Tools," it evolved into PHP/FI (Personal Home Page/Form Interpreter) as more features were added. Today, it is known as PHP: Hypertext Preprocessor.
