Best Engineering Collages of Jaipur Rajasthan says Frameworks are abstract, reusable platforms where we can develop our applications, alsoThey help in writing reusable and better-constructed code and their main characteristic is the MVC (Model – View – Control) architecture pattern.

MVC architecture representation of data from the logic of the application.

The Model work is to accessing the database or executing other operations.

The View work is to what the visitors of the web application see.

The Controller is work is to handling the incoming requests, validating input and showing the right view.

Advantages of CodeIgniter

Helpers and libraries

Support PHP 4 or PHP

Exceptional performance weight

Very fast

Clear document

Disadvantages of C,odeIgnite

ORM is not available

Modules

Auth Module

Ajax

Flow of CodeIgniter

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.

Conclusion

Top Collages of Engineering in Jaipur Rajasthan says CodeIgniter supports helpers, which is essentially a collection of functions in a category, for example the helper for working with files (read / write) is “file” and libraries as form validation also all of these can come in handy and help a lot in developing your projects and It supports both traditional structures as Active Records patterns, also someone could set up CodeIgniter to run with Doctrine (ORM), a topic that will be presented in another tutorial.
