**Course Title:** Mastering CodeIgniter Framework: Fast, Lightweight Web Development **Section Title:** Introduction to CodeIgniter and Development Setup **Topic:** Exploring CodeIgniter's directory structure **Introduction:** In the previous topics, we have covered the overview of CodeIgniter, its features, and setting up the development environment. We have also explored the MVC architecture in CodeIgniter. Now, it's time to dive deeper into the framework's directory structure, which is essential for understanding how CodeIgniter organizes its files and folders. **Understanding CodeIgniter's Directory Structure:** CodeIgniter's directory structure is well-organized and follows a specific pattern. The directory structure can be broadly categorized into several main folders: * **application**: This folder contains the core application code, including controllers, models, views, and other application-specific files. * **system**: This folder contains the core framework files and should not be modified. * **public**: This folder contains the public-facing files, such as index.php and other entry points for your application. Let's explore each of these folders in more detail: * **application**: * **config**: This folder contains configuration files, such as database settings, URL settings, and more. * **controllers**: This folder contains the controller classes, which handle the application's business logic. * **models**: This folder contains the model classes, which interact with the database. * **views**: This folder contains the view files, which are responsible for rendering the application's user interface. * **libraries**: This folder contains custom libraries or reusable code that can be used across the application. * **helpers**: This folder contains custom helper functions that can be used across the application. * **system**: * **core**: This folder contains the core framework files, including the base controllers, models, and views. * **database**: This folder contains the database drivers and other database-related files. * **libraries**: This folder contains the core libraries, such as the pagination and email libraries. * **helpers**: This folder contains the core helper functions, such as the string and array helpers. * **public**: * **index.php**: This file serves as the entry point for your application. * **.htaccess**: This file contains the rewrite rules for your application. **Key Takeaways:** 1. The **application** folder contains the core application code, including controllers, models, and views. 2. The **system** folder contains the core framework files and should not be modified. 3. The **public** folder contains the public-facing files, such as index.php and other entry points for your application. **Practical Application:** To apply this knowledge, try creating a new CodeIgniter project and explore the directory structure. Create a new controller, model, and view to get a feel for how the directory structure is organized. **Example Code:** Here is an example of a basic controller file: ```php // File: application/controllers/Home.php defined('BASEPATH') OR exit('No direct script access allowed'); class Home extends CI_Controller { public function index() { $this->load->view('home'); } } ``` And here is an example of a basic view file: ```php // File: application/views/home.php <html> <head> <title>Home Page</title> </head> <body> <h1>Welcome to the Home Page</h1> </body> </html> ``` **Conclusion:** In this topic, we have explored CodeIgniter's directory structure and learned about the different folders and files that make up the framework. We have also applied this knowledge by creating a new controller, model, and view. **What's Next:** In the next topic, we will explore **Understanding CodeIgniter’s routing system** and learn how to configure routes in CodeIgniter. For further information about CodeIgniter, please refer to the [CodeIgniter Official Documentation](https://codeigniter.com/user_guide/). **Do you have any questions about this topic?
