Introduction To CodeIgniter
CodeIgniter is one of the best open source and the most rapid development framework software which is used for building dynamic web apps and websites in PHP language. This framework is based on the 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 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.
Definition of CodeIgniter
CodeIgniter is rightfully defined as the open-source software which is used to rapidly develop the web framework so that it can be put to use in the creation of dynamic web pages and web sites in PHP language.
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 an elegant toolkit in order to create fully featured and functional web applications. The goal of this application is 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 are also loaded dynamically at the run time upon giving a particular request and thereby making the base system quite fast and lean.
What Can You Do With CodeIgniter?
The use of CodeIgniter can be seen in many places such as its feature about making use of MVC which helps in keeping 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 also you are getting all the tools in one single 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. Own libraries and helper libraries could also be developed by the CodeIgniter community. It also consists of the 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 the 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 which forms the computing unit of the framework but the model and the view part forms the optional parts. Another feature which makes working with CodeIgniter fun is that it generates cleaner URLs which is 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.
