Beyond Frameworks
The document discusses the limitations posed by software frameworks and proposes a layered architecture approach for PHP applications. It emphasizes the importance of creating independent, reusable components while minimizing dependency on frameworks, allowing for easier maintenance and development. The author advocates for a component-based strategy that enhances flexibility, scalability, and collaboration among development teams.
