What is PHP?
PHP, which stands for Hypertext Preprocessor, is a widely used open-source server-side scripting language specifically designed for web development. Created in 1994 by Rasmus Lerdorf, PHP has evolved significantly over the years, becoming a powerful tool for creating dynamic and interactive web pages. It is embedded within HTML code and executed on the server, which allows developers to create content that interacts with databases, manages sessions, and handles form submissions seamlessly.
Brief History and Evolution of PHP
PHP began as a set of CGI binaries written in C, which Rasmus Lerdorf used to maintain his personal homepage. He released it to the public in 1995 as “Personal Home Page Tools.” As its popularity grew, a development team formed, leading to the release of PHP/FI (Forms Interpreter) in 1997, which introduced the ability to communicate with databases and incorporate basic functionality directly into HTML.
The language underwent major transformations with the release of PHP 3 in 1998, which was a complete rewrite, and the establishment of the “PHP: Hypertext Preprocessor” recursive acronym. PHP 4, introduced in 2000, brought significant performance improvements with the Zend Engine 1.0. PHP 5, released in 2004, added robust object-oriented programming capabilities, and PHP 7, released in 2015, delivered substantial performance enhancements and reduced memory consumption. PHP 8, released in 2020, introduced the Just-In-Time (JIT) compilation feature, further boosting performance.
Importance of PHP in Web Development
PHP’s popularity stems from its simplicity, flexibility, and extensive support. It powers over 78% of all websites whose server-side programming language is known, including major platforms like WordPress, Facebook, and Wikipedia.
