Build a Simple REST API in PHP

This example shows how to build a simple REST API in core PHP and secure it with Okta using OAuth 2.0 Client Credentials Flow.

Please read https://developer.okta.com/blog/2019/03/08/simple-rest-api-php to see how this application was built.

Prerequisites: PHP, Composer, MySQL, Okta developer account

Okta has Authentication and User Management APIs that reduce development time with instant-on, scalable user infrastructure. Okta's intuitive API and expert support make it easy for developers to authenticate, manage, and secure users and roles in any application.

Getting Started

Sign up for an Okta developer account and create a new application. Make note of the Client ID and Issuer values for your application.

Clone this project using the following commands:

[email protected]:oktadeveloper/okta-php-core-rest-api-example.git
cd okta-php-core-rest-api-example

Configure the application

Create the database and user for the project:

mysql -uroot -p
CREATE DATABASE api_example CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'api_user'@'localhost' identified by 'api_password';
GRANT ALL on api_example.* to 'api_user'@'localhost';
quit

Copy and edit the .env file and enter your database details and Okta details there:

cp .env.example .env

Install the project dependencies and start the PHP server:

composer install
cd public
php -S 127.0.0.1:8000

Loading 127.0.0.1:8000/person should return a 401 Unauthorized response now.

NOTE: if using a virtual machine and NAT, you might need to run the server as php -S 0.0.0.0:8000 -t public instead.

Run the client application

In the public directory, simply run:

php client.php

If you see 'Obtaining token...success!' on the first line then Okta authentication is working correctly. After that, you should see the client app execute some API requests and dump the output.
