WorkerMan向特定客户端Push数据

说明：这个例子只能单进程，要支持多进程或者服务器集群的话需要Channel组件完成进程间通讯，开发也非常简单，可以参考Channel组件集群推送。

代码：

use  Workerman\Worker;

require_once '/WorkMan/Workerman/Autoloader.php';

$worker = new Worker('text://0.0.0.0:6666');

$worker->count = 1;

$worker->conn_ids = array();

$worker->onMessage = function($connection,$data)use($worker) {

          //设置id和连接的映射

          if(!isset($worker->conn_ids[$connection->id])) {

                      $worker->conn_ids[$connection->id] =$connection;

                      return$connection->send('login success, your name is user_'.$connection->id);

           }

          //解析参数

          list($id,$message) = explode(':',$data);

         //校验参数...

         //全局广播or给特定id发送

         if($id==='all') {

                    broadcast($connection->id,$message);

          }else{

                    sendMessageById($connection->id,$id,$message);

          }

};

//当有客户端连接断开时

$worker->onClose=function($connection)use($worker) {

          if(isset($worker->conn_ids[$connection->id])) {

                   //连接断开时删除映射

                   unset($worker->conn_ids[$connection->id]);

           }

};

//向所有验证的用户推送数据

function broadcast($from_id,$message) {

           global $worker;

           if(!empty($worker->conn_ids) && count($worker->conn_ids) >1) {

                    foreach($worker->conn_idsas$conn) {

                                $conn->send("user_{$from_id}say '{$message}' to all\n");

                     }

            }else{

                     $conn=$worker->conn_ids[$from_id];

                     $conn->send("Hi，user_{$from_id}。No one online\n");

           }

}

//针对id推送数据

function sendMessageById($from_id,$to_id,$message) {

            global$worker;

            if(isset($worker->conn_ids[$to_id])) {

                      $conn=$worker->conn_ids[$to_id];

                      $conn->send("user_{$from_id}say '{$message}' to user_{$to_id}\n");

             }else{

                      $conn=$worker->conn_ids[$from_id];

                      $conn->send("Hi，user_{$from_id}。user_{$to_id}is not online\n");

            }

}

Worker::runAll();

效果如下：

一、启动脚本

二、连接

三、断开user_2的连接
