php-slim 3.12.3-4 (amd64 binary) in ubuntu hirsute

 Slim is a PHP micro framework that helps you quickly write simple yet
 powerful web applications and APIs. At its core, Slim is a dispatcher
 that receives an HTTP request, invokes an appropriate callback
 routine, and returns an HTTP response. It is an ideal tool to create
 APIs that consume, repurpose, or publish data, and great for rapid
 prototyping.
