What is CodeIgniter Framework?

What is CodeIgniter Framework?

CodeIgniter is a powerful PHP framework with a very small footprint, built for developers who need a simple and elegant toolkit to create full-featured web applications.

How does CodeIgniter Work?

CodeIgniter is an MVC framework. MVC stands for Model View Controller. When a user requests a resource, the controller responds first. The controller understands the user request and then requests the necessary data if necessary.

Codeigniter

For example, if you want to retrieve a customer with the id= 3, the controller will receive your request, then request the CodeIgniter models to retrieve the record with the id of 3. The CodeIgniter models will return the record to the controller. The controller then forwards the result to the view which formats it into a human-readable format. Then the results are returned to the user in the browser.
