gRPC

gRPC is a high-performance, open-source Remote Procedure Call (RPC) framework that is increasingly used in PHP applications for building efficient and scalable microservices. Unlike traditional REST APIs that use JSON over HTTP, gRPC uses Protocol Buffers for serializing structured data and leverages HTTP/2 for faster, more robust communication between services.

PHP Development with gRPC

A PHP developer in a gRPC-focused role is responsible for defining service contracts and data structures using .proto files. From these definitions, they generate PHP server and client code. The core task involves implementing the server-side logic for the defined RPC methods, ensuring low latency and high throughput for internal service-to-service communication.

Key Skills and Concepts

• Understanding of Protocol Buffers (Protobuf) for schema definition.
• Experience generating PHP code from .proto files.
• Implementing unary, client-streaming, server-streaming, and bidirectional-streaming RPCs.
• Knowledge of integrating gRPC services with PHP frameworks like Symfony or Spiral.
• Familiarity with service discovery, load balancing, and authentication in a microservices architecture.
