Why build a custom PHP framework:

1. Satisfy specific requirements: Each project has unique needs; a generic framework may not fit, so a custom framework can be tailored for flexibility and project‑specific solutions.

2. Learning and growth: Developing a framework hands‑on deepens understanding of underlying principles and mechanisms, enhancing technical mastery.

3. Long‑term maintenance: Owning the core code simplifies bug fixes, reduces version‑migration issues, and avoids external dependencies.

4. Performance optimization: Tailoring the framework to project characteristics can improve performance.

5. Ease of use and maintenance: Customizing to team coding habits boosts development efficiency and simplifies upgrades.

6. Security: A self‑made framework allows tighter control over security aspects.
