What is CodeIgniter?

CodeIgniter is an open-source web application framework written in PHP. That is used to develop web applications quickly and efficiently. By providing a set of tools for common tasks such as database access, form validation, and session management.

CodeIgniter development is known for its small footprint, simple setup, and easy-to-learn, elegant syntax. It is often used for developing dynamic websites, content management systems, and e-commerce platforms.

How CodeIgniter Works?

CodeIgniter follows the Model-View-Controller (MVC) architectural pattern, which separates an application’s data (Model), user interface (View), and control logic (Controller) into separate components. Here’s a brief overview of how CodeIgniter works:

1. The user interacts with the View component, which sends requests to the Controller.

2. The Controller receives the requests, processes them, and interacts with the Model to retrieve or modify data as needed.

3. The Model communicates with the database or other data sources to perform data-related tasks such as querying, updating, or deleting data.

4. Once the Model has retrieved or modified the data, it sends it back to the Controller.

5. The Controller then passes the data to the appropriate view. Which generates the appropriate HTML, CSS, and JavaScript code for a display to the user.

6. The user interacts with the View again, and the process repeats.

CodeIgniter includes a number of helper classes and libraries that can be used to streamline common tasks. For example, form validation, file uploading, and email sending. CodeIgniter supports a number of third-party plugins and libraries. Which can be easily integrated into a CodeIgniter application to extend its functionality.
