Spark is a PHP micro-framework that follows the Action-Domain-Responder (ADR) system. It is PSR-1, PSR-2, PSR-4 and PSR-7 compliant. Spark allows a developer to fairly quickly create a RESTful API as you'll see in this article.
In this article, we'll be using Composer to install Spark and other dependencies.
Using Composer, pull down the Spark project using the following command. This will pull the latest version of the project from Github and place it into a new folder called 'spark-project'.
