📘 History, Features and Uses of PHP
📜 History of PHP
What is the history of PHP?
PHP stands for Hypertext Preprocessor. It is a server-side scripting language designed mainly for web development.
PHP was created in 1994 by Rasmus Lerdorf. At first, PHP was not a full programming language. It was a simple set of tools written in C to track visitors on his personal website. He named it Personal Home Page Tools.
Later, developers saw its potential. PHP slowly evolved into a powerful scripting language capable of handling databases, forms, sessions, and complete websites.
Why PHP was created
PHP was created to solve a real problem. Websites were static and boring. Developers wanted pages that could change content automatically based on user input. PHP made this possible without complex setups.
