Introduction To CodeIgniter
CodeIgniter is rightfully defined as the open-source software used to rapidly develop the web framework to be put to use in the creation of dynamic web pages and websites in PHP language. CodeIgniter is one of the best open source and the most rapid development framework software used to build dynamic web apps and websites in PHP language. This framework is based on loosely coupled systems and makes use of the widely popular MVC, i.e. Model View Controller framework and development pattern. The controller classes are, in fact, a crucial part of the development phase and pattern; the models and the views are an optional entity. The CodeIgniter can also be used to modify the Hierarchical Model View Controller (HMVC), thereby allowing developers to maintain a modular level of grouping of controllers, views, and models specifically arranged in a subdirectory format. This framework is most of the times noted down for its vibrant speed and quick responsiveness as compared to other PHP frameworks.
Understanding CodeIgniter
CodeIgniter is an extremely powerful PHP framework with a very small footprint, specially built for developers who need to make use of a simple and elegant toolkit in order to create fully featured and functional web applications. This application aims to enable the users to develop the projects a lot faster and quicker than if you would have chosen to write your code from scratch. It is used to do this by providing a rich set of libraries for the commonly needed applications and tasks. Doing this is also possible because of the varied usage of the simple interface and the logical structure which is present to access the set of these libraries.
How Does CodeIgniter Make Working so Easy?
CodeIgniter is lightweight in nature as the core system requires the use of very few libraries which is in stark contrast to many other web frameworks present today, which requires the use of significantly more resources. The other set of libraries is also loaded dynamically at the run time upon giving a particular request, thereby making the base system quite fast and lean.
What Can You Do With CodeIgniter?
CodeIgniter can be seen in many places, such as its feature of making use of MVC, which helps keep the code separate and things cleaner. As it works along well with little to almost no server requirements, all the PHP 4 and PHP 5 related apps can get benefitted from CodeIgniter. This is very easy to understand, extend, and get all the tools in one package; therefore, its usage can be seen in creating emails, calendars, uploading, unit testing, validation, sessions, etc. It also includes several other features and formats such as things like forms, arrays, file handling, cookies, strings, directories and more. The CodeIgniter community could also develop its own libraries and helper libraries. It also consists of built-in security tools and other features such as unsetting all the global variables irrespective of PHP directives. It can also be used in forms of abstraction of database and much more.
Working with CodeIgniter
CodeIgniter gives you the option to creatively focus on the project by lessening the amount of the code being put to use required for a particular task. It is free to use, so you don’t have to worry about your pocket as it is licensed under MIT licensing, so you can use it any way you wish to use it. It is a way to fast, and therefore all the output generated is a lot quicker and fast. The effective use of the MVC architecture, where it makes use of the Model and View along with the controller, has always been making things easier and a lot more interesting. The controller is an essential component that forms the framework’s computing unit, but the model and the view part forms the optional parts. Another feature that makes working with CodeIgniter fun is that it generates cleaner URLs, one of the most essential and important factors. These URLs are also user-friendly and search engine friendly. It does not make use of the standard query string parameter approach but a synonymous approach which is a more efficient way for browsers.
