PHP SOLID

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.
