Create proto file

syntax = "proto3";

package grpc.api;

service PingService {
    rpc Ping (PingRequest) returns (PingResponse) {}
}

message PingRequest {
    string message = 1;
}

message PingResponse {
    string message = 1;
}

Generate php code

protoc --php_out=src --grpc-web_out=mode=grpcwebtext:src --proto_path=config/proto 

Create controller

<?php

namespace App\Controller\Grpc;

use App\Grpc\Api\PingRequest;
use App\Grpc\Api\PingResponse;
use Haskel\GrpcWebBundle\Attribute as Grpc;

#[Grpc\Service('PingService', package: 'grpc.api')]
class PingService
{
    public function Ping(PingRequest $request): PingResponse
    {
        $message = $request->getMessage();
        
        $response = new PingResponse();
        $response->setMessage("pong:" . $message);
        
        return $response;
