Answer
Reflection inspects classes, methods, and parameters. Useful for dependency injection containers and ORMs.
Quick Answer
Reflection API inspects classes, methods, properties, and parameters at runtime. Use ReflectionClass to get class metadata, list methods, read annotations/attributes. Useful in DI containers (auto-resolve constructor params), testing frameworks (access private members), ORM mappers, and plugin systems. Powerful but slow - cache reflection results in production. Avoid in hot paths.
