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.

Controller Implementation

Let's first add proper code in the PostControllerindex() method that will return actual data. But to see data coming in response, it is better to insert some dummy data in the users, posts and tables. A better way to do this is to write seeds for that. However, if you don't want to look into how to write seeds then you can insert it manually for now.

Here is an implementation of the index() method:

public function index(\App\Post $post)
    return $post->paginate(20);

Here, paginate(20) means that it will return a paginated result with the limit of 20. And as you can see, we have used dependency injection to get the Post object. This is something that we have already discussed in this chapter.

Similarly, we will have PostController other methods implemented here. This is what the PostController code will look like:


namespace App\Http\Controllers;

use Illuminate\Http\Request;

class PostController extends Controller

    public function __construct...
