The MVC architecture (Model-View-Controller) is one of the most popular patterns in PHP development because it provides a clear structure for organizing code and simplifying the development of WEB applications. While basic MVC principles are sufficient for most web applications, it has some limitations for applications that need to handle complex data or implement advanced functionality. Separating the model layer Separating the model layer is a common technique in advanced MVC architecture. It involves breaking down a model class into smaller subclasses, each focusing on a specific functionality.
