Home Backend Development PHP Tutorial PHP Pthread socket 获取全局静态对象里的对象值

PHP Pthread socket 获取全局静态对象里的对象值

Jun 20, 2016 pm 12:39 PM

我想问一下 PHP Pthread用法

我现在在弄打牌游戏  客户端跟 服务端 都写好了

现在能打牌多人对玩都可以  不过 socket 用的是单线程的 

打牌时候有人没出牌的话 就得停顿一下
反正得很多地方用sleep
就是sleep一下
那整个服务器就卡了  因为是单进程单线程的。。
所以想解决这个问题 我打算用pthread  一个玩家就是一个线程 就是 玩家对象里存放 线程 然后方便通信跟延时
 我用了一下Thread  运行以后好像直接不能跟 主进程拿数据  或者可不可以 一个玩家对象是线程
因为没太用过线程不清楚怎么实现思路也就不清晰了 也不知道可不可以实现

请高手给个思路 卡一周了 都开发完了 又不能换语言 然后 服务器是 windows 因代码太多 简单自己贴下代码  **星号处不能获取
然后有好的 思路 告诉一下  就是sleep停顿跟 通信部分。。。。。
class WaittingRoom{
  public static $Rooms= array();
  public static $Gamers = array();
  public function addGamer($gamer_id){
    db查询
     self::$Gamers = new Gamer($gamer_id);
  }
}
WaittingRoom::addGamer("game_id");

class Connection extends Thread {
    public $connection;
    public $uid = null;
    public $is_free;
public function __construct($client){
$this->is_free = false;
$this->connection = $client;
$this->start();
}

connections = array();
do{
   有连接的话
   connections [] = new Con($sockit);
}while

class Con(){
       public function __construct($client){
$this->connection = $client;
$this->start();
}
        public run(){
            while($this-connection读数据){
                然后这里 处理数据
                处理数据时候 掉用 全局静态变量
              ******  WaittingRoom::$Gamers[标识]->指定函数或者变量都不能获取导数据  DB操作也不行 ********
                 
            }

        }
}

你的思路好像有问题吧?也可能是我道行较浅无法理解你的多线程是如何工作的
一个 socket 服务端只能侦听一个端口,你用多线程怎么设侦听端口?用户如何知道那个端口是空闲的?

你说大量使用了 sleep,这是为什么?
既然有循环等待(我猜的),那么 sleep 必将拖慢处理过程

如果不幸被我猜中的话,那么你使用的是点对点的 socket 架构
按你描述的应用,应使用 select 架构(点对多点):
创建主侦听 master
将其加入连接字列表 sockets[] = master
在永久循环中(说死循环不好听):
   获取连接字列表副本 changed = sockets
   读取各连接字状态 socket_select(changed) (由于 socket_select 会改变 changed 的内容,所以上一步要取副本)
   socket_select 只在连接字列表有变化时才会返回,所以就不需要 sleep 等待了
   遍历有效的连接字列表 foreach(changed as socket)  :
       if(socket == master) 通常表示有新连接请求,将 socket 加入 sockets,并作应答
       else 表示某用户有数据传入,读取并作应答 

你可以看到,这个架构并不是你想象的那么复杂吧

理解    你说的那部分已经实现了 socket 接收数据是没问题的  多个用户也是可以接受数据     接到数据 并用那个数据 创建的对象 也就是  在读写操作的服务器页面里  创建了对象   大厅对象  房间对象  玩家对象   大厅里存放玩家跟 房间对象  当要玩游戏的时候 就进入房间  往房间对象里放入  玩家对象   然后玩家齐了之后  并开始游戏  创建  裁判对象 也就是游戏引擎 游戏引擎里  得  结果运算
发牌事件同步等问题   得等待1两秒钟  里面还有 电脑。。。。电脑不给  sleep的话  都看不到 发牌直接就轮到你 发牌了 。。

唉说了一大堆 自己语言水平有限。。。 就是WEB页面的话  一个用户一个页面。。  不过socket的话  多个用户 在一个页面里读写
一个页面给sleep的话  直接 进入的全部玩家跟房间里的玩家 都接收不到数据   所以得多线程处理   
现在主要就是不太会多线程。。 多出来的线程sleep 不会影响   主线程。。 其他用户可以读写数据
然后现在 贴代码时候。。 遇到了  线程里不能读取 全局对象里 。。。。 创建的对象。。。 也就是  玩家对象。

没有方法吗  在线等

如果你需要使用多线程时,要
       if(socket == master) 通常表示有新连接请求, 在这里启动一个线程,完成 将 socket 加入 sockets,并作应答
       else 表示某用户有数据传入, 在这里启动一个线程,完成 读取并作应答 

主线程负责调度,子线程负责操作
