PHP started in 1994 as a set of C tools Rasmus Lerdorf wrote to track visits to his online CV, released publicly in 1995 as “Personal Home Page Tools”. Andi Gutmans and Zeev Suraski rewrote the parser for PHP 3, and their Zend Engine has powered PHP since version 4. The name now stands for the recursive “PHP: Hypertext Preprocessor”.
After the abandoned PHP 6, PHP 7 (2015) brought a large speed-up, and PHP 8 added a JIT compiler and modern language features. Releases now come out every November. Each version gets two years of active support and two years of security fixes. The PHP Foundation, formed in 2021, pays core developers, and Composer and frameworks such as Laravel and Symfony make up the modern ecosystem.
