1.	Features of CodeIgniter:
Answer» CodeIgniter is an open-source and powerful MVC(Model-View-Controller) based framework used for developing web applications on PHP. CodeIgniter provides libraries for connection with the database and to perform OPERATIONS such as sending emails, uploading files, managing sessions, etc. It helps for PHP code simplification and brings out a fully interactive, dynamic website in a shorter span of time. The latest VERSION of CodeIgniter is CodeIgniter4 version v4.1.3 which was released on June 6, 2021. CodeIgniter features will include the following: Framework with a small footprint: Source code for the CodeIgniter framework is nearly 2MB in size. It makes it easier to master CodeIgniter and how it works. In addition, it simplifies deploying and updating it. Loosely coupled: The built-in features are designed to work independently without depending too much on any other components. This makes it easier for maintaining and upgrading. MVC Architecture: CodeIgniter framework uses the MVC architectural design. MVC architecture separates the data, business logic, and presentation. Blazing fast: Users opt for applications that load very fast. If you have worked with few modern frameworks, you will realize that it takes LESS than one second to load immediately after installation. You can load CodeIgniter on average AROUND less than 50ms. Excellent and clear documentation: CodeIgniter framework is having well-maintained documentation. Also, it has good tutorials, books, and answered forum questions on this. This implies whatever challenge you are facing, chances are someone has previously encountered the problem, solved it and the solution is available for you. Extendable: CodeIgniter includes several libraries and helpers out of the box. If what you want is not there or you wish to implement an existing feature your way, then you can do so easily by creating your own libraries, packages, helpers, etc. You are also permitted to create REST API in CodeIgniter. Application-specific built-in components: It has components for sending email, session management, database management, and much more. Short learning curve: CodeIgniter is easy to master for anyone who knows PHP. Within a shorter period, the student can learn CodeIgniter and start professional applications development using CodeIgniter. Scope of CodeIgniter: CodeIgniter is a PHP framework with a significantly small footprint, specifically built for developers who want to make use of a SIMPLE and graceful toolkit for creating completely featured and functional web applications. This application focus on enabling the users to develop the projects much faster and quicker than if you would have gone for writing your code from scratch. It is used for doing this by providing a set of libraries for the commonly needed applications and tasks. It provides services for all the application modules to access the application database or external information resources in an OOP manner. Here, the model classes will have the functions that help us to insert, update, and retrieve information in the database.
