In this article, I will take you through a brief history, current libraries, and PHP 5.

PHP has always been an ever-expanding web programming language, ever since it’s initial release on June 8th, 1995. PHP initially began as a bunch of CGI binaries written in C deemed “Personal Home Page Tools” (PHP tools). Two years later, Andi Gutmans and Zeev Suraski, the founders of Zend Technologies, took Rasmus Lerdorf‘s PHP-FI (PHP’s version 2) and rewrote the parser, giving birth to PHP 3 (now called Pre-Hypertext-Processor). In 1998, the parser was redesigned once again and named the Zend Engine, and the popular PHP 4 was released in the May of 2004.
