protobuf-phpとソケットの使い方

この記事では、protobuf-php とソケットの使用方法を主にコードの形式で説明します。

vi login.proto

package login;
message ReqCheckVerifyVerLoginClient
{
 required int32 game = 1; ///< 游戏类型编号 required bytes version = 2; ///< 游戏版本号}
message AnsCheckVerifyVerLoginClient
{
     required uint32 ret_code = 1;  //返回码     optional uint32 forbid_flag = 2; //冻结时间     optional uint32 time_diff = 3;  //剩余解封时间}

protoc --plugin=/usr/local/php/bin/protoc-gen-php --php_out=. -I.login.proto

login.php

namespace login {  class ReqCheckVerifyVerLoginClient extends \DrSlump\Protobuf\Message {    /**  @var int */    public $game = null;    
    /**  @var string */    public $version = null;    
    /** @var \Closure[] */    protected static $__extensions = array();.........

を使用.php

function.php

<?php/** * Created by PhpStorm. * User: Administrator * Date: 2018/3/23 * Time: 19:26 */require &#39;socket.php&#39;;require &#39;structNum.php&#39;;function socket($ip,$port,$packed){    try{

        $socket->connect($ip,$port);        if(count($packed) >1){            foreach ($packed as $key){
                $sockResult = $socket->sendRequest($key);// 将包发送给服务器                sleep(3);
            }
        }
        $getrepost = $socket->getResponse();
        $socket->disconnect (); //关闭链接    } catch (Exception $e) {
        var_dump($e);
        $this->log_error(" error send to server".$e->getMessage());
