Origin & Creator

Created by Rasmus Lerdorf in 1995 as ‘Personal Home Page Tools’. It evolved into PHP 3/4 with Zend Engine, then PHP 5 introduced OOP, PHP 7 delivered massive performance improvements, and PHP 8 added JIT compilation, attributes, union types, enums, fibers, and major language modernization.

Industrial Note

PHP dominates the CMS ecosystem-WordPress, Drupal, Joomla. It powers Laravel and Symfony large-scale enterprise apps, e-commerce platforms like Magento, and millions of shared-hosting-based businesses. Used by Meta (legacy), Slack internal tools, Mailchimp, Etsy, and Wikipedia.
