I just finished building a comprehensive SOLID principles tutorial in PHP, and I'm really proud of how it turned out! 🎉
https://github.com/bedwards/php-solid
What started as a learning exercise became something I think the community will find valuable. Here's what I built:
Deep Educational Content: I didn't just explain what each SOLID principle is—I dove into why it matters, what problems it solves, and how the principles interconnect. Each section explores real scenarios and demonstrates the difference between following and violating the principles.
Clean, Practical Examples: Every principle has minimal yet complete code examples that demonstrate the concept without unnecessary complexity. The implementations follow PHP best practices with proper typing and clear structure.
Comprehensive Testing: Integration tests verify actual behavior across all principles, with good coverage of both success and failure scenarios.
Professional Setup: PHPStan at level 10, PHPUnit 12, automated testing via GitHub Actions—the whole project represents real-world PHP development standards.
Thoughtful Design Choices: I'm particularly happy with the Interface Segregation example, which uses a document workflow with Draft/Published/Archived states and segregated Readable/Writable/Printable interfaces. It demonstrates the principle naturally without feeling contrived.
The repository includes everything: detailed explanations, working code, tests, and CI/CD setup. It's the kind of resource I wish I'd had when I was first learning these concepts.
