CodeIgniter is an open-source software rapid development web framework, for use in building dynamic web sites with PHP.
How CodeIgniter Works?
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 then request the necessary data if necessary.
For example, if you want to retrieve a customer with the id= 3, the controller will receive your request, then request the model to retrieve the record with the id of 3. The model returns 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.
