PHP stands for Hypertext Preprocessor. It is a server side scripting language created to develop dynamic and interactive websites. PHP was originally developed in 1994 by Rasmus Lerdorf. At first, it was a simple set of tools used to track visits to his personal website. Later, it evolved into a full programming language used worldwide for web development.
Over time, PHP became one of the most popular backend languages due to its simplicity, flexibility, and strong community support. Major versions of PHP introduced powerful improvements in performance, security, and modern programming features.
Today, PHP is maintained by The PHP Group and continues to power millions of websites including content management systems and eCommerce platforms.
