PHP MicroServices Examples

This is a repo of example MicroServices using PHP. Areas of topics will include:

• Socket Programming
• RabbitMQ Example
• RESTFUL Example
• Authentication and Authorization Example
• Functional Programming Example

Many of the examples use ProdigyView Toolkit for development.

Requirements To Run Test

1. Composer
2. PHP7
3. PHP Sockets Extensions Installed

E-Mail and Socket Programming

Overview

The mail microservice uses basic socket communication between a socket server and service. For explanation, please read: PHP Microservices — Send Emails Over Sockets

How To Run

1. Go to the email folder
2. Run composer install to install required packages
3. Open up two tabs in your console
4. In one tab, run php server.php
5. In the other tab, run php client.php

Video Processing and RabbitMQ

Overview

The services shows a basic example of how to create a service for processing videos with RabbitMQ. For detailed explanation of the service, please visit: PHP Microservices — Video Processing With RabbitMQ

How To Run

1. Ensure RabbitMQ is installed and running locally
2. Go to the video folder
3. Run composer install to install required packages
4. Open up two tabs in your console
5. In one tab, run php server.php
6. In the other tab, run php client.php

Restful Crud API

Overview

This tutorial will demonstrate how to create a basic REST api for processing CRUD operation at an endpoint. For detailed information, please visit: PHP Microservices — Creating A Basic Restful Crud API

How To Run

1. Go to the rest folder
2. Run composer install to install required packages
3. Open up two tabs in your console
4. In one tab, we need to start a php server with php -S 127.0.0.1:8080
5. In the other tab, run php client.php

Organizing Access To Microservices

Overview

This section will show how to organize and manage multiple microservices. The past 3 examples have been combined into one, with the addition of sending pushing notifications and image processing. The goal is to give each service their own resources, and organize calling them via REST API.

For detailed work through please read Organizing Access To Multiple Services.

How To Run

We will need four tabs to effectively run this example.

1. Start your RabbitMQ Server
2. Go the the multiple folder
3. Run composer install to install required packages
4. Have your four tabs open to this folder
5. Start the webserver with php -S 127.0.0.1:8090 in one tab
6. Start the notification server with php servers/notification_server.php in the 2nd tab
7. Start the media server with php servers/media_server.php in the 3rd tab
8. Execute the tests by running php client.php in the last tab

Authentication, Authorization, Functional Programming and Unit Tests

Overview

This part of the tutorials covers how to perform Authentication and Authorization between microservices. It also includes an additional information on how to do function programming and unit test. Accompanying tutorial are as followings:

• Authentication And Authorization
• Functional Programming and Unit Testing

How To Run The Microservice

Running this example requires 4 tabs on your console.

1. Go to the security folder.
2. Run composer install to install required packages
3. Make sure your 4 tabs are open in this directory
4. Start the web server with php -S 127.0.0.1:8000
5. Start the authentications server with php authentication_service/server.php
6. Start the purchase server with php payment_server/server.php
7. Run the client with php client.php in the final tab

How To Run Tests

1. Go to the security folder.
2. Run composer install to install required packages
3. Type ./vendor/bin/phpunit --bootstrap vendor/autoload.php tests/AuthenticationServerTest.php for Authentication Tests.

Socket vs HTTP Performance

Overview

This tutorial and test will bring you through comparing the performance of a RESTFUL API vs Sockets. You may read along about the tests here: REST vs Socket Performance Benchmarks

How To Run

This test will require that 3 tabs open.

1. Go to the socket_vs_http folder.
2. Run composer install to install required packages
3. Have your 3 tabs open
4. In your first tab, start the web server with php -S 127.0.0.1:8000 -t http_server/
5. In the second tab, start the socket with php socket_server/server.php
6. In the final tab, run the client with php client.php
