CodeIgniter for Web Development – An Ultimate Guide In 2023

Website development can appear difficult, especially if undertaken without support. Fortunately, development tools such as CodeIgniter exist. The British Columbia Institute of Technology maintains a PHP framework with a simple yet effective toolkit for developing web applications.

What is CodeIgniter?

CodeIgniter is a PHP framework that allows you to create dynamic features and advanced functionality with little coding or complexity. It employs a Model View Controller (MVC) framework to make development more manageable.

  • MVC is a software development approach in which the application logic is separated from the presentation. In the procedure, your web pages can have minimal scripting because the user interface is distinct from the PHP scripting.
  • The MVC pattern aims to separate business logic from the user interface, resulting in more composable code.
  • When the MVC pattern is used, the Controller acts as a bridge between the Model, which contains the application data, and the View, which is in charge of the presentation.
  • When a CodeIgniter receives a request, it goes to the index.php page to see if it can be served from the cache location or if it requires it to go to the database.
  • The user receives an immediate response if the requested resource is in the cache. If the resource is not found in the cache, it is routed to the application controller.
  • The application control then takes the responsibility of loading the view class data along with the necessary models, libraries, and plugins.. The View class formats the data into a readable output and displays it to end users via a web browser.

Features of the CodeIgniter framework

CodeIgniter development company Australia is one of the most popular web development frameworks because of its comprehensive set of features and functions of the system.

Here are some of the most notable features of CodeIgniter.

MVC Modeling 

As we’ve seen, MVC helps to separate application logic from the front-end user interface, making CodeIgniter applications more effective and reliable. MVC also supports test-driven development, allowing developers to create and test individual modules for improved results. MVC streamlines the development process and allows for the seamless integration of JavaScript frameworks.

Built-in Libraries

CodeIgniter supports a large library catalogue that provides important and dynamic features and functions for web applications. These libraries help in the execution of numerous functions such as file uploads, email dispatch, session management, database management, and so on. 

The libraries can also be dynamically loaded based on development requirements, providing developers with enhanced functionality.

Security and XSS Filter 

To ensure data security in the underlying modules, it provides a wide range of security protocols, including encryption. The framework also employs XSS filtering to identify methods for activating JavaScript code for cookie hijacking or other dangerous activities. It secures the module by transforming it into character entities.

Minimal Configuration

You don’t have to spend time configuring the environment before you start developing the various modules of your web development project when you use the CodeIgniter framework. It includes all the necessary setups and configurations to get you up and to run quickly. 

Aside from that, the zero configuration setup makes it easier to deploy CodeIgniter applications to shared hosting environments because no changes to the server configuration are required.

Comprehensive Documentation

Before deciding on a platform or technology, it is critical to consider the developer community support. The CodeIgniter user guide includes extensive documentation support, such as tutorials, guides, and component reference material, to assist developers in understanding the entire CodeIgniter framework.
