PHP (Hypertext Preprocessor) is a popular, open-source scripting language designed primarily for creating dynamic websites and web applications. It was created by Rasmus Lerdorf and is executed on the server side. PHP enables integration with databases, form handling, generating HTML content, and building complex web systems.
This language is widely used in the development of websites, CMS systems (e.g., WordPress), online stores, and web applications. Thanks to a large community and a rich ecosystem of frameworks (e.g., Laravel, Symfony), PHP remains one of the most frequently used backend languages.
