Codeigniter is an MVC (Model-View-Controller) Framework like Laravel. When a user requests any page, it will pass through the index.php.

Then the controller understands the request and retrive the necessary data.

For example, if you want to rerive a user data where id=1, the controller will received your request and send back the request to codeigniter models. Codeigniter models fetch the data from database where id=1 and CodeIgniter models will return the record to the controller. Then then controller forword all data thorugh view page to user browser in HTML human realable format.
