Implement grpc server through php roadrunner

Warehouse address:

https://github.com/zhonghaibin/php-grpc-serve

Download source code:

git clone https://github.com/zhonghaibin/php-grpc-serve

The php version I use: php 8.2

Installation command line input

composer install

Get the rr.exe executable file command line input

./vendor/bin/rr get-binary

Start the service./rr.exe serve

Client

I am using ApiPost to support grpc testing

打开apipost客户端，新建grpc,选择导入proto  

选择项目目录的 grpc/protos/base/hello-world.proto 文件

##grpc reference document:

roadrunner.dev/docs/plugins-grpc/2...

protoc construction steps

1 Create Protobuf hello according to your own needs -world.proto file

2 Generate php class file through hello-world.proto

这里需要下载两个可执行文件把 hello-world.proto 生成 php文件，

因为我用的是win10：

所以下载的是 protoc.exe 和 protoc-gen-php-grpc.exe 

这两个文件我放在项目里 protoc-22.3-win64 文件夹里面，如果你和我环境一样直接用我下载好的即可，其他平台请自行下载

下载地址：https://github.com/roadrunner-server/roadrunner/releases

生成php文件命令如下：./protoc.exe --plugin=protoc-gen-php-grpc.exe --php_out=./ --php-grpc_out=./ hello-world.proto

这里会在当前目录下生成两个文件夹：GPBMetadata 和 Services

把生成好的文件夹复制到 项目目录的 grpc/generated 目录下

├─config
├─grpc
