Meet PHP

PHP is an open-source scripting language used to build dynamic websites and web applications. Its code usually runs on a server, where it processes requests and produces HTML, JSON, or other output for a browser or client. Developers can embed PHP directly in HTML, handle submitted forms, manage sessions and cookies, and connect applications to databases through dedicated extensions or PDO.

The language supports both procedural and object-oriented programming and works across major operating systems, including Linux, Windows, and macOS. Beyond serving web pages, PHP can run from the command line for scheduled jobs, file processing, and other automation tasks. A developer can begin with a small script on a local server, then organize reusable functions and classes as the application grows.
