Learn FUELPHP with Real Code Examples
Updated Nov 27, 2025
Explain
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.
Core Features
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
Basic Concepts Overview
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
Project Structure
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
Building Workflow
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
Integrate modules/packages for reusable features
Difficulty Use Cases
Beginner: Simple web pages with HMVC controllers
Intermediate: CRUD applications with ORM
Advanced: RESTful API with modular packages
Expert: Large-scale modular HMVC application
Architect: Enterprise system integrating multiple modules and packages
Comparisons
FuelPHP vs Laravel: HMVC modularity vs full-featured MVC
FuelPHP vs Symfony: Lightweight and modular vs enterprise-grade
FuelPHP vs CodeIgniter: HMVC support vs traditional MVC
FuelPHP vs Slim: Modular HMVC vs micro-framework simplicity
FuelPHP vs Yii: Flexibility and packages vs advanced tooling
