Overview of this book

REST is the most wide spread and effective standard to develop APIs for internet services. With the way PHP and its eco-system has modernized the way code is written by simplifying various operations, it is useful to develop RESTful APIs with PHP 7 and modern tools. This book explains in detail how to create your own RESTful API in PHP 7 that can be consumed by other users in your organization. Starting with a brief introduction to the fundamentals of REST architecture and the new features in PHP 7, you will learn to implement basic RESTful API endpoints using vanilla PHP. The book explains how to identify flaws in security and design and teach you how to tackle them. You will learn about composer, Lumen framework and how to make your RESTful API cleaner, secure and efficient. The book emphasizes on automated tests, teaches about different testing types and give a brief introduction to microservices which is the natural way forward. After reading this book, you will have a clear understanding of the REST architecture and you can build a web service from scratch.

Creating RESTful Endpoints

So far, we have understood what a RESTful web services. We have also seen the new features in PHP7 which will make our code better and cleaner. Now, it is time to implement RESTful web services in PHP. So, this chapter is all about implementation.

We have seen an example of a blog having blog posts and comment endpoints. In this chapter, we will implement those endpoints. Here are the topics that we will cover:

Creating REST API for a blog in PHP
- Creating a database schema
  - Blog user/author table schema
  - Blog post table schema
  - Blog post comments schema
- Creating REST API's endpoint
  - Code structure
  - Common components
  - Creating blog post endpoints
  - To do
Visible flaws
- Validation
- Authentication
- Proper 404 pages
