What is CodeIgniter Framework?
CodeIgniter is a popular PHP framework for constructing web applications rapidly. It is an implementation of the popular Model-View-Controller(MVC) pattern.
While controller classes are an essential component of development, It also comes with pre-built libraries for connecting to the database and performing various tasks, such as sending emails, uploading files, managing sessions, etc.
Modifications of CodeIgniter can make use of Hierarchical Model View Controller (HMVC) that allows the developers to arrange Controller, Model, and View in a sub-directory format.
Its speed is generally praised when contrasted to other PHP frameworks. Rasmus Lerdorf, the PHP creator, criticized frameworks in general, stating at frOSCon in 2008, that he liked CodeIgniter because it is faster, lighter, and least like a framework.”
History Of CodeIgniter
EllisLab released CodeIgniter’s first public version on February 28, 2006. EllisLab announced on July 9, 2013, that it was seeking a new owner for CodeIgniter, citing a lack of resources to properly support the framework.
In October 2014 EllisLap announced the continuation of CodeIgniter development by the British Columbia Institute of Technology. Since October 23, 2019, It has been under the care of the CodeIgniter Foundation and is no longer under the foster care of the British Columbia Institute of Technology.
Codeigniter 4 was released on February 24, 2020, the birthday of Jim Parry, the project leader of CodeIgniter 4 who passed away on January 15, 2020. The project has continued since then with another project lead.
Why Do We Implement CodeIgniter In Our Applications?
Check out some of the great features that CodeIgniter has. In this list are outlined the major features of working with it, but they are not exhaustive.
The entire source code for CodeIgniter is less than two megabytes. This makes it easier to learn and more straightforward to use. Additionally, it simplifies setting it up and updating it.
There is a tendency for users to select applications that load quickly. Since modern frameworks load within fewer than one second after installation, you will have experienced this. It loads in around 50 milliseconds on average. It frees up the extra time you would otherwise spend optimizing.
Free to Use
The framework is developed by the Massachusetts Institute of Technology and is for free use.
Follow the MVC structure:
The application uses MVC that separates logic and presentation. A request is sent to the controller, the action is completed in the database through the model, and output is then displayed through views.
Create SEO friendly URLs:
One of the great features of Codeigniter is that it uses a segment-based approach rather than the traditional query-based approach. Because they are search engine friendly, they don’t cause problems.
Codeigniter comes with built-in libraries that are designed to aid web tasks such as database, form validation, and email sending.
Some advanced features are:
1- Security and XSS Protection.
3- Error reporting.
4- Data encryption, file upload, page management, session management.
5- Zip encoding class.
6- Flexible URI Routing.
7- Full-page caching.
