Flow of Code Igniter

User enters the URI of the project then CI gets the request and checks the routes file to find any matches, and If a match is found so it triggers the right Controller and function also the Controller calls the right Model to retrieve / create the data needed,, After the data is retrieved the Controller finds the right View and returns it and View and data is represented to the user

Controller is triggered

 It should be shown to the visitor and then it returns that View with the corresponding data.

This is defined by routes also Routes is a PHP configuration file that maps each URL of our web project to a Controller and a certain function.
