For building a web application you spend tons of your time writing an equivalent code again and again. Frameworks provide you with a block and minimize the number of codes needed to create a website.
CodeIgniter is an open-source web framework for PHP. It is an Open Source framework, licensed under MIT License and its source code is maintained at GitHub. It has a really rich set of functionality, which can increase the speed of website development work.
If you are well familiar with PHP, then CodeIgniter will make your task easier. It’s a very rich set of libraries and helpers. By using CodeIgniter, you’ll save tons of your time, if you’re developing a website from scratch. Not only that, a website inbuilt CodeIgniter is secure too because it has the power to stop various attacks that happen through websites.
There is a large demand for the CodeIgniter framework among PHP developers because of its versatile features and advantages. A web application developed on CodeIgniter performs productively and quickly. It provides a sophisticated set of aspects to write down from scratch to create a dynamic web application.
It is licensed under the MIT license, so it’s liberal to use.
It uses Model-View-Controller architectural design which basically separates logic and presentation parts. The request involves the controller, database action is performed through the model, and output is displayed through views.
But in PHP scripting, every page represents MVC which increases complexity.
It is extremely light-weighted. CodeIgniter core system requires a very small library and other libraries could also be added upon dynamic request based on your needs. That’s why it’s quite fast and lightweight weighted.
URLs generated by CodeIgniter are search-engine friendly and very clean. It uses a segment-based approach instead of a standard query-based approach.
It comes with full packet libraries that enable all the online needed tasks like database, form validation, sending email, manipulating images, sending emails, etc.
Users tend to favor applications that load in no time. If you’ve got worked with a number of the fashionable frameworks, then you’ll realize that they take less than one second to load just after installation. CodeIgniter, you’ll load on average around less than 50ms. The additional time spent optimizing is that the case in another framework is freed up once you are working with the CodeIgniter framework.
The built-in features are designed to work independently without relying an excessive amount on other components. This makes it easy to take care of and make better.
The framework is well documented, and there are good books, tutorials, and answer forum questions on CodeIgniter. This suggests whatever challenge that you simply have, chances are someone has already encountered the matter, solved it and therefore the solution is out there for you.
It comes with some libraries and helpers out of the box. If what you want is not there otherwise you would like to implement an existing feature your way. Then you’ll be able to do so easily by creating your libraries, helpers, packages, etc. you’ll also create REST API in CodeIgniter.
CodeIgniter is straightforward to master for anyone who is already familiar with PHP. Within a very short time, the scholar can learn it and begin developing professional applications using it.
CodeIgniter is created to deliver maximum performance in less time within a clean environment. To achieve this, each developing process is created in a very simplified way.
From the technical point of view, it’s dynamically instantiation (libraries are loaded for the asking which makes it light-weighted), loose coupling. (Components rely very less on each other) and component singularity (each class and its functions are closely focused only on their purpose).
