Pop PHP Framework

The Pop PHP Framework a free and open source PHP Web framework that was created by Nick Sagona. It is distributed under the BSD License and hosted on GitHub. The framework is intended to be utilized for rapid application development, with an emphasis on web applications.
History.
Development on the Pop PHP Framework was officially begun by Nick Sagona in late 2011, when he refactored a set of older library components into the first version of Pop PHP, which was released on March 19, 2012. The focus was for Pop PHP to become a more modern, MVC-style web framework with a set of supporting components to assist in building web applications.
After PHP 5.4 was released, Pop PHP 2 was refactored to take advantage of the new features available in PHP 5.4, as well as fully leveraging Composer by breaking out almost all of the components into separate repositories on GitHub. Pop PHP 2 was first released on July 12, 2015.
Pop PHP 3 was a slight refactor of the existing framework, while adding a handful of new components and deprecating a few older components. Version 3 supports PHP 7 and 5.6 and was released on July 9, 2016. The last version, 3.8.0, was released on August 25, 2018. The EOL version 3.8.9 was released on February 24, 2020.
Pop PHP 4 was another refactor of the existing framework that upgraded and improved existing components. Version 4 supports PHP 7.3 or greater and PHP 5.6 is no longer supported. The current version, 4.6.0, was released on February 12, 2021.
The framework has been included on a number of "best of" lists for new and up-and-coming PHP Frameworks.
The Pop PHP Framework is the framework on which the open source Phire CMS project was built.

Development.
While the initial development of the Pop PHP Framework was focused on building web applications, since version 3, Pop PHP fully supports console-based applications to be used on the CLI as well. Pop PHP incorporates current standards, trends and patterns in software development in an attempt to build an ecosystem that is familiar to developers. The framework is heavily unit-tested using PHPUnit and runs through the Travis CI continuous integration platform to ensure the builds of the individual framework components are passing.
Pop PHP 4 is currently written for and supports PHP 7.3.
The Pop PHP Framework project welcomes community involvement and contribution via the current available channels.
Features.
The base foundation of Pop PHP is the initial set of core components that make up the application stack:
Additionally, there are a number of other components that are available for use in building an application. Some of the commonly used components and what they include are:
Popcorn.
Popcorn is a standalone web-based component that serves as a REST-based micro-framework layer to allow developers to quickly build REST-based web applications and APIs. With it, a developer can enforce routes by request methods and direct HTTP requests accordingly.
Kettle.
Kettle is a CLI-based helper script available since version 4.0.1. It allows the user to quickly scaffold application files and folders together as well as manage databases and migrations.
