CodeIgniter is an free and open-source software rapid development web framework, for use in building dynamic web sites with PHP. [5]
CodeIgniter is loosely based on the popular model–view–controller (MVC) development pattern. While controller classes are a necessary part of development under CodeIgniter, models and views are optional. [6] CodeIgniter can be also modified to use Hierarchical Model View Controller (HMVC [7] ) which allows the developers to maintain modular grouping of Controller, Models and View arranged in a sub-directory format.
CodeIgniter is most often noted for its speed when compared to other PHP frameworks. [8] [9] [10] In a critical take on PHP frameworks in general, PHP creator Rasmus Lerdorf spoke at frOSCon in August 2008, noting that he liked CodeIgniter "because it is faster, lighter and the least like a framework." [11]
CodeIgniter's source code is maintained at GitHub, [12] and as of the preview version 3.0rc, is certified open source software licensed with the MIT License. Versions of CodeIgniter prior to 3.0.0 are licensed under a proprietary Apache/BSD-style open source license. [13]
A 2011 decision to switch licensing to the Open Software License (OSL) sparked some community controversy, [14] especially about the GPL incompatibility of the new license, to which EllisLab has responded with a series of articles entitled Software License Awareness Week. [15]
The first public version of CodeIgniter was released by EllisLab on February 28, 2006. [16]
On July 9, 2013, EllisLab announced that it was seeking a new owner for CodeIgniter, citing a lack of resources to give the framework the attention they felt it deserved. [17] On October 6, 2014, EllisLab announced that CodeIgniter would continue development under the stewardship of the British Columbia Institute of Technology. [18] As of October 23, 2019, with the CodeIgniter Foundation taking the reins, CodeIgniter is no longer under the care of the British Columbia Institute of Technology. [19]
CodeIgniter 4 was released On February 24, 2020, [20] the birthday of Jim Parry, the project lead of CodeIgniter 4, and who died on January 15, 2020. [21] Since then, the project continues with another lead.
PHP is a general-purpose scripting language geared towards web development. It was originally created by Danish-Canadian programmer Rasmus Lerdorf in 1993 and released in 1995.

PHP was originally an abbreviation of Personal Home Page, but it now stands for the recursive initialism PHP: Hypertext Preprocessor.
Squeak is an object-oriented, class-based, and reflective programming language. It was derived from Smalltalk-80 by a group that included some of Smalltalk-80's original developers, initially at Apple Computer, then at Walt Disney Imagineering, where it was intended for use in internal Disney projects. The group would later go on to be supported by HP Labs, SAP, and most recently, Y Combinator.

The framework is basically a collection of professional PHP-based packages. The framework uses various packages by the use of Composer as part of its package dependency managers; some of them are PHPUnit for testing all packages, Travis CI for continuous Integration Services. Laminas provides to users a support of the model–view–controller (MVC) in combination with Front Controller solution. MVC implementation in Laminas has five main areas. The router and dispatcher functions to decide which controller to run based on data from URL, and controller functions in combination with the model and view to develop and create the final web page.

PeachPie is an open-source PHP language compiler and runtime for the .NET Framework and .NET. It is built on top of the Microsoft Roslyn compiler platform and is based on the first-generation Phalanger project. PeachPie compiles source code written in PHP to CIL byte-code. PeachPie takes advantage of the JIT compiler component of the .NET Framework in order to handle the beginning of the compilation process. Its purpose is not to generate or optimize native code, but rather to compile PHP scripts into .NET assemblies containing CIL code and meta-data. In July 2017, the project became a member of the .NET Foundation.
