Why build a custom PHP framework:

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

2. Learning and growth: Developing your own framework provides a deep understanding of underlying principles and mechanisms, enhancing mastery of low‑level technologies.

3. Long‑term maintenance: Owning the core code makes it easier to maintain, fix bugs, and avoid version‑migration or dependency issues associated with third‑party frameworks.

4. Performance optimization: Developers can fine‑tune the framework to the project's characteristics, achieving better performance.

5. Ease of use and maintenance: A framework aligned with the team’s coding habits improves development efficiency and simplifies future upgrades.

6. Security: A custom framework allows tighter control over security aspects.
