Slim

Slim is a PHP microframework that helps you quickly write simple yet powerful web applications and APIs. Essentially, Slim is a dispatcher that receives an HTTP request, calls the appropriate callback procedure, and returns an HTTP response. Slim is the perfect tool for building APIs that consume, reconfigure or publish data. Slim is a great tool for rapid prototyping, you can even create fully functional web apps with user interfaces. Importantly, that Slim is very fast and very lightweight. In fact, you can read and understand its source code. You don't always need a solution like Symfony or Laravel. These are great tools, of course. But they are often very large. Instead, Slim only provides a minimal set of tools that do what you want, and nothing else.
