CodeIgniter Tutorial — CI MVC Framework

CodeIgniter Tutorial: Codeigniter provides a PHP framework based on this. As a result, it has a reusable capability, and it has also employed MVC in this framework (model view controller ).

Here, we’ll walk you through all of the points and concepts related to Codeigniter, as well as how to create a project with a lot of features. How to utilise CodeIgniter and format using the Codeigniter function is also covered.

So, below is each Codeigniter answer provided by web learn smart. A Codeigniter document containing an example is also available.

Codeigniter Tutorial step by step

What is Codeigniter?

As a result, Codeigniter is a free web application framework. It must also provide the developer with robust tools. It can be used in a friendly manner for any task.

It manages and creates pieces of assistance in the development of sophisticated web applications with more structure and programming design.

For a better web application, Codeigniter offers more than just its own functionality of reusable source code.

Why We use Codeigniter

For web applications, we should mostly use Codeigniter, which is a sophisticated framework. It includes a PHP open-source framework, as well as additional Codeigniter features.

With the help of Codeigniter, developers may create reusable code.

For web applications, it has a well-known PHP framework. All source codes are provided, as well as a step-by-step instruction manual. Visit the official Codeigniter webpages. User manual for Codeigniter Installing instructions

How to Install Codeigniter

Here are certain actions to take, and make sure you follow them.

Go to Google and type in Codeigniter; we’ve provided a link to download CodeIgniter. Then, navigate to the server directory and place these download files there.

If you’re running a local wamp/xampp server, make sure the www file is present.

Codeigniter is the default file name. You have the option to change the project name.

Codeigniter File Structure

In this folder, there are two sorts of files: default and user, which we utilise for custom code users. The image file structure is visible.

After that, it’s time to move on to the tools. First and foremost, we employ user-friendly tools. So, in these files, click application files, and you’ll see that there are more than files, as seen in the figure above.

Cache:- So the cache data is defined by the files at the top of the cache.

Config:- There are several sub-files in this file, so I’ll explain how to use them. We can utilise database files because this is an automatic crate database code, so we simply have to do the database name.

This config file only uses the file paths in the directories that we use in our own projects.

Libraries:- Default tools such as form and database are used in these files.

Similar libraries, such as validation card and URL, are included in this file.

How to use MVC (Model View Controller) in Codeigniter

The model view controller is a programming structure that is used by developers. This structure is really handy and beneficial. This pattern allows you to simply regulate codes.

1. Model: This is the back end when you’re writing database query and login code in this file. So, first, you create a model file in which you also include your class and function.

2. View:- It’s a user interface that solely mentions front end area codes.

3. Controller: The controller is used to control both the file model and the display, as well as the user’s response and action. It also mentions login in these files.

Now that we’ve covered all aspects of the Codeigniter tutorial, you’ll need to set up the Codeigniter framework and learn how to use it.
