Building and Testing PHP Microservices With Semaphore

Microservices architecture, which involves breaking down monolithic applications into smaller, independent services, has gained popularity for its scalability and adaptability in large-scale web applications. This detailed guide demonstrates how to build and test PHP microservices using Laravel, Docker, and MySQL, focusing on creating a Product service and an Order service, where the Product service informs the Order service. The guide outlines steps to set up databases, configure environment variables, create models, migrations, and controllers, and set up API routes. It also covers testing the microservices with PHPUnit to ensure functionality and reliability, using Tyk as an API gateway for communication between services, and integrating Semaphore for continuous integration and deployment. Through practical examples, readers learn how to map APIs to gateways and automate testing and deployment pipelines, thereby enhancing the development process and ensuring high-quality microservices deployment.
