What Are Libraries In CodeIgniter?

The purpose of a library is to provide a convenient, reusable, and well-tested solution to a common problem. It should provide a well-defined API, meaning a set of functions that are easily accessible to a developer. A library should not include any logic on its own. It should be able to be used independently from the framework or programming language it was developed in.

CodeIgniter has several libraries that can use in your application. The libraries are designed to do specific tasks and many libraries do the same task. This means that you can choose the one that suits your needs best. For example, there are 2 libraries for sessions. The first is a native session handler that uses cookies and maintains the session on the server. The other is a session handler that uses the database to store the session data. Both perform the same task but one uses cookies and the other uses the database.
