Overview
Both Laravel and CodeIgniter are open-source PHP frameworks that follow the Model-View-Controller (MVC) architectural pattern. This pattern promotes organized code by separating the application’s concerns:
- Model: Handles data and business logic.
- View: Manages the presentation layer and user interface.
- Controller: Acts as an intermediary between the Model and View, handling user requests and data processing.
While both frameworks share this foundation, they differ significantly in their features, complexity, and overall approach to web development.
Laravel
Created by Taylor Otwell in 2011, Laravel has gained immense popularity for its elegant syntax, robust features, and developer-friendly environment. It emphasizes developer experience and modern PHP development practices. Laravel is a leading PHP framework, holding a significant market share of 35.87%. In 2024, Laravel’s download count exceeded 50 million, with download statistics increasing by 15-20% per year.
Key Features of Laravel
- Blade Templating Engine: Provides a simple, yet powerful templating system with an intuitive syntax for creating dynamic and reusable views. Blade templates are compiled into plain PHP code, which effectively reduces the rendering time.
- Eloquent ORM: Offers an intuitive and expressive way to interact with databases, simplifying database operations and relationships. Eloquent ORM provides an ActiveRecord implementation for working with your database. Each database table has a corresponding “Model” which is used to interact with that table.
- Artisan Command-Line Interface: Provides helpful commands for tasks like generating code, managing databases, and running tests.
- Robust Security Features: Includes built-in protection against common vulnerabilities like cross-site scripting (XSS), cross-site request forgery (CSRF), and SQL injection. Laravel uses “providers” and “guards” to facilitate the authentication process. Guards authenticate users for each request they make, while providers retrieve users from your database.
Advantages of Laravel
