Pop PHP is an open source, object-oriented PHP framework with humble beginnings dating back to 2009, where it started as a small library of components. The first official version of Pop was released in early 2012. Version 2 was release in 2014, and version 4.0.1 is the current live version in production.
The focus of Pop is to provide a robust set of lightweight tools to assist developers with rapid application development. With a relatively small learning curve, Pop aims to help developers in getting the features they need into their applications so they can be up and running quickly.
Popcorn is available as a micro-framework layer that can be utilized to build REST applications and APIs. It utilizes only a few of the web-based components, although any of the other components can be added at any time. With Popcorn, a developer can enforce routing rules based on request methods and quickly wire up a REST-based application.
