#codeigniter tutorial for beginners

I completely understand your trepidation about learning codeigniter. Confused, what do I need to know, and where do I begin? The good news is that in this tutorial, I'll show you how to get started with codeigniter from scratch. Step by step, please. If you're a beginner. This CodeIgniter tutorial will be a success with you.

Codeigniter is a Web Application Framework (WAF) that was created to make it easier for web developers to create web-based apps.

Codeigniter is a framework that consists of a collection of code in the form of libraries and utilities. Rick Ellis, the creator of EllisLab, created Codeigniter in 2006 as a web framework for the PHP programming language. Ellislab is a working group that began in 2002 and specialises on software development and web developer tools.

From 2014 to the present, EllisLab has granted ownership rights to codeigniter to the British Columbia Institute of Technology (BCIT) for ongoing development. Many tools (facilities) in Codeigniter assist PHP developers in creating web applications quickly and efficiently.

Codeigniter is more flexible and has a simpler design.

Codeigniter enables web developers to use the framework in part or in its entirety.

This means that Codeigniter tutorial for beginners still allows the developer to write certain elements of the app's code in the traditional manner.

Model-View-Controller (MVC) is a design or architecture pattern used by Codeigniter that separates code portions for business process handling from code sections for presentation.

This design pattern enables web developers to collaborate on web-based applications (teamwork).

As a result, site developers can concentrate on their individual tasks without interfering with the work of others.

As a result, the developed application will be completed more quickly.

Codeigniter Advantages:

The following are some of CodeIgniter's benefits:

1. Codeigniter is a PHP framework that is free to use.

2. In comparison to other frameworks, Codeigniter is compact. The Codeigniter framework is only roughly 2 MB in size after installation.

3. Codeigniter-based applications are quick to run.

4. Codeigniter employs the Model-View-Controller (MVC) design paradigm to avoid cramming too much code into a single file. This makes it easier to read, understand, and maintain the code in the future.

5. Codeigniter may be scaled to meet your needs.

6. Codeigniter The documentation supplied in the distribution package contains well-documented information about the libraries and functions provided by codeigniter.

7. Codeigniter comes with an extensive library and helper.

8. Codeigniter's security features include xss filtering, session encryption, and more.

9. Codeigniter allows web developers to use libraries or helpers that codeigniter does not provide, such as Google Map API, Facebook API, fpdf, and others.

10. Codeigniter has a lot of flexibility. As a result, web developers will be able to create web-based apps without the use of a framework.

11. Codeigniter has a wide community and is used by web developers all around the world, making it easier for them to address challenges when developing web-based apps.

12. Many RDBMS (Relational Database Management Systems) are supported by Codeigniter, including MySQL, SQL Server, Oracle, Maria DB, Wordpress, SQLite, and others.

13. Codeigniter essentially supports SEO and welcomes Clean URLs (Search Engine Optimazation). As a result, popular search engines such as Google, Yahoo, MSN, and others find it easier to index codeigniter-based applications.

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

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 StructureIn 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 CodeigniterThe 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.
