Hello World, Today i am going to create a custom library in codeigniter 3. Library refers to a class which is location in application/libraries folder. This folder contains only user defined libraries. Codeigniter have their own library which is located in system/libraries.
We should not modify the core library of any framework or any CMS becuase when you will update your system, your changes will disappear. Codeigniter provides facility to extend the core library classes and add some additional feature in it. In codeigniter, we can perform following things with library.
- Create library from scratch
- Extend the functionality of existing library
- Replace the functionality of existing library
