Introduction

Generate PHP protobuf code using PHP ./protoc-gen.php -o build tests/test3.proto

The generated message code is meant to work with Google protobuf's official PHP implementation: https://github.com/google/protobuf/tree/master/php

The generated service client code is meant to work with gRpc https://grpc.io/docs/quickstart/php.html#prerequisites

Requirements

• Unix/Linux system
• PHP >= 7.0 and composer installed
• Only support proto3 syntax proto file
• protoc installed, version >= 3.5

Usage

• composer require liues1992/php-protobuf-generator

• ./vendor/bin/protoc-gen.php --out=build --grpc_out=build tests/*.proto or use directly as plugin:

  protoc --php-custom_out=build --plugin=protoc-gen-php-custom=./vendor/bin/protoc-gen-plugin.php \ --grpc-php_out=build --plugin=protoc-gen-grpc-php=./vendor/bin/protoc-gen-grpc-plugin.php tests/*.proto

• See the example folder for the generated code

Run test

composer test

TODO

• More test case
• Pack to phar
• Support proto2
• Custom generator support (write your own code generators by require this package)

Why do I need this instead of Google's default implementation?

• Sometimes you wish to customize the generated code, which is complicated to do if you modify google/protobuf source code(c++) and recompile the protoc binary. Think about above situations:
  • Add convenience methods in message class..
  • Support proto2
  • Generate custom rpc code (if you are not using gRpc or you want it to use in PHP server side)
• Some bug in Google's generated code.

 public function setEnum($var) { // GPBUtil::checkEnum accepts only on param GPBUtil::checkEnum($var, \Gary\Test\Foo_Enum::class); $this->enum = $var; return $this; } 

• Cool to generate PHP code using PHP (easy for PHP developers to join).

How does it work

That's a secret. Find out yourself.
