This tutorial uses a deprecated micro-framework called Silex. The fundamentals of REST are still ?valid, but the code we use can't be used in a real application.
Making RESTful APIs is hard, really hard. There are a lot of concepts to know - resources, representations, HTTP methods, status codes, etc.

And putting this all to life in a sane way in PHP is no small task. In this course, we'll learn all the most fundamental concepts around REST and learn about the "rules" and the advantages and disadvantages of each. And we'll of course build a real API to show it all off. Topics include:

HTTP basics
Resources and Representations
Resource state, client state
GET, POST, PUT, PATCH, DELETE
Idemptotency and safe methods
Proper Status Codes, Location header and Content-Type
Testing your API
RFCs and where the "rules" come from
Advanced error and validation handling
If you want to know about Hypermedia, HATEOAS, Content-Type negotiation, pagination and more, these are not covered here, but are covered in Episode 2.

This tutorial uses Silex and we avoid talking about it as much as possible and instead focus on the core concepts of REST. Once you understand these, you can watch our Symfony REST series to learn how to leverage Symfony for your API.
