Introduction to CodeIgniter
CodeIgniter is a powerful PHP framework built for developers who need a simple and elegant toolkit to create full-featured web applications.

MVC (Model-View-Controller)
MVC stands for Model-View-Controller. MVC is an application design model consisting of three interconnected parts. They include the model (data), the view (user interface), and the controller (processes that handle input).

Sessions
The Session class allows you to maintain a user’s "state" and track their activity while they browse your site.

URI Routing
There is a one-to-one relationship between a URL string and its corresponding controller class/method. The segments in a URI normally follow this pattern:

Forms and Input
Forms provide a way for users to interact with the application and submit data.

Composer
Composer is dependency manager in PHP. it allows you to declare the libraries your project depends on and it will manage (install/update) them for you.

Security
You can enable CSRF protection by modifying your application/config/config.php file

Working with Database
Like any other framework, we need to interact with the database very often and CodeIgniter makes this job easy for us. It provides a rich set of functionalities to interact with the database.

Example
Sign in, Send an email and Upload a file

AJAX Example
Insert and Update Operations

DataTable
DataTables is a table enhancing plug-in for the jQuery Javascript library that helps in adding sorting, paging, and filtering abilities to plain HTML tables with minimal effort. The main goal is to enhance the accessibility of data in normal HTML tables.

Spreadsheet
PhpSpreadsheet is a PHP library for reading and writing spreadsheet files. Importing Excel and CSV into MySQL help to save the user time and avoid repetitive work.

Payment Gateway
Razorpay and PayTM Payment Gateway

Chatbot
WhatsApp Chatbot and Telegram Chatbot
