What is CodeIgniter framework (PHP) ?

PHP is very popular among programmers and is currently the most widely used server-side language globally. The PHP language alone fully meets the needs of programmers, but sometimes programmers turn to them for the benefits of PHP frameworks. One of the most popular PHP frameworks is CodeIgniter. CodeIgniter is very powerful and helps PHP programmers to design and program a web application with a wide variety of capabilities in a short time and without much complexity. In this article, we examined what a CodeIgniter framework is and its uses.

History of the Codeigniter framework

The well-known software company EllisLab released CodeIgniter for the first time on February 28, 2006. The initial version of this service was nothing more than a few general-purpose classes taken from the ExpressionEngine project (a content management system built by EllisLab). But over time, CodeIgniter got bigger, and new features were added. Although the PHP framework market is hot today, CodeIgniter has long demonstrated the power of the PHP programming language and its potential for building frameworks.

EllisLab announced in July 2013 that it did not have the necessary conditions to maintain and develop the CodeIgniter and decided to transfer ownership of the CodeIgniter. Less than a year later, on October 6, 2014, ownership of the framework was transferred from EllisLab to the British Columbia Institute of Technology.

Disadvantages of CodeIgniter framework

Although CodeIgniter has many advantages, like all services globally, it has its disadvantages. Of course, these disadvantages are not so great or important that you should stop using this framework. One of the problems with CodeIgniter is code retention. Clean and modular coding is very important for software companies today. In this way, they can easily update their product in the future or add new features to it. CodeIgniter does not support module separation by default, unlike other modern PHP frameworks. As a result, other developers who want to work on our project later may have problems. Another drawback is the libraries of this framework, which are less numerous and diverse than their competitors.

Size and security of the Codeigniter framework

Codeigniter is a lightweight and compact framework. The download file of Codeigniter version 3 is less than three megabytes in size. CodeIgniter has high security; for example, this framework comes with an XSS security filter to prevent XSS attacks or cross-site scripting. Or another common attack on the web is SQL Injection, which targets the database. In PHP, a function called mysql_real_escape_string () is defined to address this, but CodeIgniter uses libraries and built-in functions to prevent SQL Injection attacks.
