FuelPHP uses HMVC, an extension of MVC, allowing for nested controllers and modular applications.

It is designed to be lightweight yet powerful, with built-in security features and flexible configuration.

Provides a rich set of libraries, helpers, and packages for database access, authentication, caching, and more.

FuelPHP emphasizes convention over configuration but allows developers to override defaults easily.

Supports RESTful API development, ORM (via its ActiveRecord-like ORM), and package-based modular development.

HMVC pattern - nested controllers and modularity

ORM - ActiveRecord-style object-relational mapping

Auth package - flexible authentication and authorization

Caching - multiple drivers including file, Redis, Memcached

REST support - build APIs with built-in helpers

Controller - handles requests and application logic

Model - interacts with database via ORM or query builder

View - renders output (HTML, JSON, XML)

Module - encapsulates features for HMVC structure

Package - reusable library or component

fuel/app/ - application-specific code (controllers, models, views)

fuel/core/ - framework core

fuel/packages/ - third-party or custom packages

fuel/public/ - publicly accessible assets

fuel/app/config/ - configuration files

Define routes in `fuel/app/config/routes.php`

Create controllers for handling logic

Create models for database operations

Build views for presentation or API responses
