Iris vs Symfony: What are the differences?

# Key Differences Between Iris and Symfony

Iris is a lightweight web framework that focuses on simplicity and performance, while Symfony is a full-stack PHP framework that provides a large set of reusable components and tools.
Iris uses a flexible routing system that allows for dynamic route patterns and subdomains, whereas Symfony uses a traditional routing system with routing configuration defined in YAML or XML files.
Iris follows a minimalist approach, providing only core functionality out of the box, while Symfony comes with a wide range of built-in features like security, form handling, and translation services.
Iris emphasizes modern PHP practices and leverages the PSR-7 HTTP message interfaces, while Symfony is known for its extensive documentation and strong community support.
Iris is more suitable for small to medium-sized projects that require high performance, whereas Symfony is ideal for large enterprise-level applications with complex requirements.
Iris has a smaller learning curve due to its simplicity and minimalist design, whereas Symfony may have a steeper learning curve for beginners due to its extensive feature set and configuration options.

In Summary, Iris and Symfony differ in terms of simplicity, routing systems, built-in features, modern PHP practices, target project size, learning curve, and community support.
