MVC Architecture
Understand the role of models, views and controllers and how they work together in a web application.
Practical CodeIgniter Training for PHP Developers
CodeIgniter is a PHP framework that helps developers organise application code and build maintainable web applications. Its MVC approach separates application responsibilities into models, views and controllers, making it easier to structure features and manage changes.
This training path introduces the framework step by step, from project setup and request routing to database-driven pages, form processing, validation, sessions and reusable application components. Practical exercises can be adapted to your existing PHP knowledge and project goals.
