php protobuf 安装使用

refer: PHP读写protobuf3示例

一.环境
  PHP 5.6.30 Ubuntu 16.04 LTS

二.安装protobuf编译器
  cd /data/
  git clone https://github.com/google/protobuf.git

  cd protobuf  
  sudo apt-get install autoconf automake libtool curl make g++ unzip

  ./autogen.sh
  ./configure

  make
  sudo make install
  sudo ldconfig # refresh shared library cache.

 

三.安装php扩展
  cd /data/protobuf/php/ext
  /usr/local/php/bin/phpize
  ./configure && make && sudo make install
  php.ini文件: extension=protobuf.so
  php -m |grep protobuf


四.使用protobuf

To use PHP runtime library requires:

  • C extension: PHP 5.5, 5.6, or 7.
  • PHP package: PHP 5.5, 5.6 or 7.


  1.协议文件编写
    /data/protobuf/php/tests/proto/person.proto

syntax = "proto3";
package Playwhale;

message Person{
    string name = 1;
    int32  age  = 2;
    string email = 3;
    enum PhoneType{
        HOME = 0;
        MOBILE = 1;
        WORK = 2;
    }
    message Phone{
        int64 id = 1;
        PhoneType type = 2;
    }
    repeated Phone phoneNum = 4;
}

message UserList{
    string name = 1;
    repeated Person users = 2;
}

 
  2.编译协议文件
    protoc --proto_path=/data/protobuf/php/tests/proto/ --php_out=/data/protobuf/php/tests/pb /data/protobuf/php/tests/proto/person.proto

  3.测试
    a.测试文件:  /data/protobuf/php/tests/meng.php 

<?php
/**
 * Created by PhpStorm.
 * User: meng
 * Date: 18-10-17
 * Time: 下午3:26
 */
$start_time = microtime(true);
$start_mem = memory_get_usage();

include 'Autoloader.php';
use Playwhale\Person;

$from = new \Playwhale\Person();
$from->setName('jack');
$from->setAge(100);
$from->setEmail('foo bar, this is a message');
//phone
$phones = array();
$phone_obj = new \Playwhale\Person\Phone();
$phone_obj->setId(10000);
$phone_obj->setType(\Playwhale\Person\PhoneType::HOME);
$phones[] = $phone_obj;
$phone_obj = new \Playwhale\Person\Phone();
$phone_obj->setId(30000);
$phone_obj->setType(\Playwhale\Person\PhoneType::WORK);
$phones[] = $phone_obj;
$from->setPhoneNum($phones);

//$encode_data = $from->serializeToString();
$encode_data = $from->serializeToString();
printf("encode_data=%s\n", $encode_data);
printf("from: phoneNum=%s\n", json_encode($from->getPhoneNum()));
file_put_contents('data.bin', $encode_data);
echo "\n";
echo "\n";

$to = new \Playwhale\Person();
$to->mergeFromString($encode_data);
printf("name=%s\n", $to->getName());
printf("age=%s\n", $to->getAge());
printf("email=%s\n", $to->getEmail());
foreach ($to->getPhoneNum() as $tmp_phone_obj) {
    printf("phone: id=%s, type=%s\n", $tmp_phone_obj->getId(), $tmp_phone_obj->getType());
}
echo "\n";
echo "\n";

$end_time = microtime(true);
$end_mem = memory_get_usage();
$mem = ($end_mem - $start_mem) / 1024 / 1024;
printf("\nlast seconds=%ss, lost_mem=%sm ok.\n", $end_time-$start_time, $mem);

 
    b.Autoloader.php

<?php
class Autoloader
{
    /**
     * Load files by namespace.
     *
     * @param string $name
     * @return boolean
     */
    public static function loadByNamespace($name)
    {
        $class_path = str_replace('\\', DIRECTORY_SEPARATOR, $name);
        if (strpos($name, 'Google\\') === 0 || strpos($name, 'GPBMetadata\\') === 0) {
            $class_file = __DIR__ . '/../src/'. $class_path. '.php';            //如果通过php扩展使用protobuf,则这里的处理可以忽略.
        } elseif (strpos($name, 'Playwhale\\') === 0) {
            $class_file = __DIR__. '/pb/'. $class_path . '.php';
        }

        if (!is_file($class_file)) {
            if(strpos($name, 'GPBMetadata\\') === 0)
                $class_file = __DIR__. '/pb/' . $class_path . '.php';
        }

        if (is_file($class_file)) {
            include_once($class_file);
            if (class_exists($name, false)) {
                return true;
            }
        }
        return false;
    }
}

spl_autoload_register('Autoloader::loadByNamespace');

 
    c.测试
      /usr/local/bin/php -dxdebug.remote_enable=1 -dxdebug.remote_mode=req -dxdebug.remote_port=9000 -dxdebug.remote_host=127.0.0.1 /data/protobuf/php/tests/meng.php

    d.测试结果
    1).使用php扩展测试:
      last seconds=0.0017640590667725s, lost_mem=0.069038391113281m ok.
      last seconds=0.0021541118621826s, lost_mem=0.069038391113281m ok.
      last seconds=0.0018389225006104s, lost_mem=0.069038391113281m ok.

    2).使用php原生语言包测试:
      last seconds=0.059786796569824s, lost_mem=1.9029998779297m ok.
      last seconds=0.10011792182922s, lost_mem=1.9029998779297m ok.
      last seconds=0.060681104660034s, lost_mem=1.9029998779297m ok.
      last seconds=0.058160066604614s, lost_mem=1.9029998779297m ok.

    3).使用php扩展有更好的性能表现,比另一个使用方法提高20到30倍

 

五.总结
  1.编写protobuf协议文件
  2.使用protoc编译协议文件,导出php语言支持的协议文件
  3.使用php扩展或php原生包,解释php协议文件
  4.推荐使用php扩展解释协议文件,有更好的性能表现.
