The SitePoint PHP blog has a new tutorial posted from author Marcello Duarte showing you how to use functional programming techniques in your applications with the help of the Phunkie library. Phunkie is a library that brings functional programming functionality to PHP. This article was originally published on the Inviqa blog.

In the first part of this series we explored parsers and combinators to help you start getting values from functional programming with PHP. We covered the basics using examples, and now we’ll move onto more sequencing and other strategies.

Continuing on, they work towards the goal of making a more useful end result, a JSON parser that returns a JsonObject. First, though, he goes through several different combinators, showing code examples for each: sequencing, choice, and recursive. He also covers the repetition pattern and how to integrate separators. Finally, with this groundwork laid, he gets to the JSON parser showing each step of the way, from reading in the JSON string to returning the object.
