Overview
PHP (originally "Personal Home Page," now a recursive acronym for "PHP: Hypertext Preprocessor") was created in 1994 and became one of the dominant languages for server-side web development. It is embedded directly into HTML, letting developers mix markup and server logic in the same file, which made it fast to pick up for building dynamic websites in the early web era. PHP scripts run on the server, processing form submissions, querying databases, managing sessions, and generating HTML that is sent to the browser. It has strong native support for talking to relational databases, which made it a natural fit for content-driven sites and applications. A large share of the web still runs on PHP indirectly through platforms built on it, most notably WordPress, which powers a substantial portion of all websites. Modern PHP (versions 7 and 8) is significantly faster and more feature-rich than its early years, with a proper type system, performance improvements, and frameworks like Laravel and Symfony that bring structured, modern application patterns to the language. Despite competition from JavaScript/Node.js and other backend languages, PHP's massive installed base and hosting ubiquity keep it in wide use for web applications and CMS platforms. It is often mentioned alongside Compiler in this space. It is often mentioned alongside Dynamic Typing in this space.
