Building Middleware Web APIs in PHP 7 with Expressive
In this tutorial we'll cover how to design and implement web APIs in PHP 7 using a middleware architecture. We'll use Expressive to implement the API leveraging the PSR-7 standard. We'll demonstrate building both simple RPC and fully RESTful API endpoints. We'll also focus on features like authentication, authorization, versioning, content negotiation, validation and filtering of user's input, and more.
