PHP Introduction

Welcome to the intriguing world of PHP, an open-source server-side scripting language that serves as the backbone of web development for many developers. With the ability to create everything from simple scripts to complex Web Softwares, PHP’s versatility is one of its many strengths.

Understanding PHP

If you’ve ever dabbled in web development, the chances are that you’ve encountered PHP, an open-source, general-purpose scripting language particularly tailored for web development, and is widely used by developers around the globe.

PHP originally stood for Personal Homepage but has evolved into a recursive acronym for ‘PHP: Hypertext Preprocessor’. The recursive nature of the acronym is in the fact that the first word itself is an abbreviation, thereby deviating from the traditional abbreviation conventions. PHP has witnessed significant evolution since its inception around 30 years ago, with its latest major version, PHP 8, released in November 2020, while PHP 7 continues to be popular.

PHP is powered by the Zend engine, the most widely used implementation, although other implementations such as Parrot, HPVM (Hip Hop Virtual Machine), and Hip Hop (created by Facebook) also exist. PHP’s primary application is in creating web servers, although it’s perfectly capable of running in the command line. So whether you prefer browser-based output or terminal display, PHP caters to both preferences.
