PHP
PHP (Hypertext Preprocessor) is a general-purpose scripting language most commonly used in web development. It allows developers to generate dynamic content, manage databases, and handle user sessions. PHP scripts run on the server and integrate easily with HTML, making it ideal for building interactive websites and web apps.
Its compatibility with various operating systems and support for multiple database systems, including MySQL and PostgreSQL, make it highly versatile. PHP is open-source, easy to learn, and backed by a strong developer community. It powers major platforms like WordPress and is frequently used for building CMS, CRM, and e-commerce solutions.
With consistent updates, including support for modern features like just-in-time compilation and strict typing, PHP remains a vital tool for backend programming.
