All that You Need to know about Codeigniter

By methods for a basic and well-designed toolkit, Codeigniter is a commanding PHP framework. If we consider web applications with advanced features, then to create such an application Codeigniter is one of the efficient PHP Frameworks. As it makes web application always ready, learning becomes easier. Also due to the usual PHP coding, it makes the code portable and only because of this, Compared to other frameworks, Codeigniter is significantly simple and fast.

Get Started with CodeIgniter

Derived from the Model-View-Controller (MVC) development pattern, it is a software approach to unscramble application logic and presentation by alienating from PHP scripting. But in reality, web pages containing minimal scripting are allowable by Codeigniter.

Why should I use a framework?

A framework is not absolutely necessary: it is “just” one of the tools that are available to help you develop better and faster!

Better, because a framework provides you with the certainty that you are developing an application that is in full compliance with the business rules, that is structured, and that is both maintainable and up-gradable.

Faster, because it allows developers to save time by re-using generic modules in order to focus on other areas. Without, however, ever being tied to the framework itself.

Why Codeigniter Framework?

Codeigniter is open source development framework that follows the MVC framework pattern. CodeIgniter goal is to allow you the straightforward and proper way to develop the project much quicker than you will do. The CodeIgniter framework provides a developer with the basic structure that helps in agile and robust web application development. CodeIgniter framework help to implement coding standards and procedures for web app development which streamlines the entire process and ensures the safety of the application. It further facilitates RAD (rapid application development) that aids with faster time to market product and reduces time and efforts significantly.

Why MVC Architecture?

For starters, MVC stands for Model, View, Controller. It is a programming pattern used in developing web apps. This pattern isolates the user interface and back-end (i.e. database interaction from each other. A successful implementation of this lets developers modify their user interface or back-end without affecting the other. MVC also increases the flexibly of an app by being able to reuse models or views over again). Below is a description of MVC.

  • Models:

A Model, which represents the underlying, logical structure of data in a software application and the high-level class associated with it. This object model does not contain any information about the user interface.

  • View:

A View, which is a collection of classes representing the elements in the user interface (all of the things the user can see and respond to on the screen, such as buttons, display boxes, and so forth)

  • Controller:

A Controller, which represents the classes connecting the model and the view, and is used to communicate between classes in the model and view.

An example of an MVC approach would be for a contact form.

  • The user interacts with the view by filling in a form and submitting it.
  • The controller receives the POST data from the form, the controller sends this data to the model
  • which updates in the database.
  • The model then sends the result of the database to the controller.
  • This result is updated in the view and displayed to the user.

This may sound like a lot of work to do. But, trust me; when you’re working with a large application, being able to reuse models or views saves a great deal of time. You can see the techniques and tricks of codeigniter at- CodeIgniter Techniques and Tricks.
