We list some of the Best Beginners\' CodeIgniter Tutorials in this article. CodeIgniter is a powerful MVC(Model-View-Controller) architecture-based PHP framework.

Frameworks are a collection of functions/procedures and classes that are ready to be used for a specific purpose in order to simplify and speed up the work of a programmer, without having to construct a function or class from scratch.

The application is divided into 3 modules by the MVC model: 

1) Model 

2) View 

3) Controller. 

In PHP, CodeIgniter is one of the most popular frameworks. Apparently, in order to create a stable web app using Codeigniter, a web developer does not need to start from scratch.

It is an elegant toolkit for creating web applications rich in functionality with the help of powerful libraries. Due to the easy learning curve, it\'s so common.

I gathered some of the Codeigniter tutorials from the web in this article to start with CodeIgniter for beginners.

You can easily develop small to large scale applications based on MVC trends with CodeIgniter. The framework of CodeIgniter is very light and easy to understand because it allows projects to be built much faster by providing a rich set of libraries for commonly necessary tasks, as well as a simple interface and logical structure for accessing these libraries.

How CodeIgniter Works?

CodeIgniter is a framework for MVC. MVC stands for Controller for Model View. The controller responds first when a user requests a resource. The controller understands the request from the user and then, if necessary, requests the necessary data.

For instance, if you want to retrieve a customer with id= 3 your request will be received by the controller then the model will be asked to retrieve the record with id= 3. 

The model gives the record back to the controller. The controller then forwards the result into a human-readable format to the view that formats it. In the browser, the results are then returned to the user.

The following are some of the advantages of MVC architectural pattern

1. ·        Loose coupling-the components exist independently of each other and function independently.
2. ·        Flexibility: modifications can easily be made to individual components
3. ·        Increased productivity: At the same time, more than one person will work on the project. Front-end developers can focus on views and presentations, while back-end developers can concentrate on models and it works at the end of the day as the system is loosely coupled.
