[PHP知识库]PHP使用protobuf3序列化常见数据格式

1.php安装protobuf3

安装过程就不详细说明，请自行百度或参考以下文档。
参考：
安装https://github.com/protocolbuffers/protobuf/tree/master/php
官网参考文档：https://developers.google.com/protocol-buffers/docs/reference/php-generated?hl=zh-cn

1.Messages
person.proto文件

syntax = "proto3";
package test;
message Person {
  string name = 1;
  int32 id = 2;
  string email = 3;
}

执行protoc --php_out=. person.proto生成php类。类的使用：

<?php
require_once 'vendor/autoload.php';
require_once 'Test/Person.php';
require_once 'GPBMetadata/Person.php';

$data=[
    'name'=>'xdf',
    'id'=>1,
    'email'=>'dfjj@dfj.com',

];
$persion=new \Test\Person($data);
$res=$persion->serializeToString();
var_export($res);

$obj=new \Test\Person();
$obj->mergeFromString($res);
echo "\n";
var_export($obj->getName());

2 嵌套Messages
person.proto文件

syntax = "proto3";
package test;
message Person {
  string name = 1;
  int32 id = 2;
  string email = 3;
  info info_msg = 4;
  
  message info{
    string phone = 1;
    string address = 2;
    int32 age = 3;
  }
}

再执行protoc --php_out=. person.proto重新生成php类。类的使用：

<?php
require_once 'vendor/autoload.php';
require_once 'Test/Person.php';
require_once 'Test/Person/info.php';
require_once 'GPBMetadata/Person.php';
$info=[
    'phone'=>'123456',
    'address'=>'xxxxxxx',
    'age'=>25
];
$data=[
    'name'=>'xdf',
    'id'=>1,
    'email'=>'dfjj@dfj.com',
    'info_msg'=>new \Test\Person\info($info)
];
$persion=new \Test\Person($data);
$res=$persion->serializeToString();
var_export($res);

$obj=new \Test\Person();
$obj->mergeFromString($res);
echo "\n";
var_export($obj->getName());
echo "\n";
var_export($obj->getInfoMsg()->getPhone());

3.Repeated
序列化带未知长度列表的数据
person.proto文件

syntax = "proto3";
package test;
message Person {
  string name = 1;
  int32 id = 2;
  string email = 3;
  repeated info info_msg = 4;
  
  message info{
    string phone = 1;
    string address = 2;
    int32 age = 3;
  }
}

再执行protoc --php_out=. person.proto重新生成php类。类的使用：

<?php
require_once 'vendor/autoload.php';
require_once 'Test/Person.php';
require_once 'Test/Person/info.php';
require_once 'GPBMetadata/Person.php';
$info=[
    'phone'=>'123456',
    'address'=>'xxxxxxx',
    'age'=>25
];
$data=[
    'name'=>'xdf',
    'id'=>1,
    'email'=>'dfjj@dfj.com',
    'info_msg'=>[new \Test\Person\info($info),new \Test\Person\info($info)]
];
$persion=new \Test\Person($data);
$res=$persion->serializeToString();
var_export($res);

$obj=new \Test\Person();
$obj->mergeFromString($res);
echo "\n";
var_export($obj->getName());
echo "\n";
var_export($obj->getInfoMsg()->count());
var_export($obj->getInfoMsg()[0]->getAddress());
