Definition: MVC stands for Model-View-Controller, which is a framework for developing web applications in programming languages such as PHP. It's similar to object-oriented programming but focuses on models (like database tables), views (view functions), and controllers (functions that manipulate data). Controllers handle logic and rendering of the application. Essentially, they're responsible for managing access to the model and view layers. The MVC framework helps developers manage complex applications and integrates well with other technologies like RESTful APIs and database integration.
