Building RESTful Web Services with PHP 7

By: Waheed ud din

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.

Finding problems in the current code

Till now, we have written our blog post's endpoint-related code, and I left to do the same with the comment-related endpoints. If you haven't done that, then I insist that you do that first, or at least try to do so because without practice, it doesn't last for much time, so keep practicing at least when some code examples are provided or there are some tasks to do.

Anyway, as we have written code to implement RESTful web service endpoints in the last chapter, we are going to dig into that and identify what is missing and what types of improvements are required.

Structural and design flaws

Right now in our code, there are some flaws we can identify very clearly.

Missing query builder layer

Although we are using PDO, we still always to write a query need to carry out many low level things such as being aware of SQL injection (due to which we have to use the prepare statement, then bind values), to perform database-related operations. We should use some...
