/**
 * 当客户端发来消息时触发
 * @param int $client_id 连接id
 * @param mixed $message 具体消息
 */
public static function onMessage($client_id, $message)
{
     //1：收到消息之后转成array()
     $data = json_decode($message,true);
     if(!$data){
       return;
     }
     //2:判断类型，bind是client_id与用户id绑定 
     //say 发送消息的事件
     switch ($data['type']) {
       //绑定
       case 'bind':
           $from_id = $data['from_id'];
           //把获取的到用户id与client_id进行绑定
           Gateway::bindUid($client_id,$from_id);
           return;
       //发送文字消息
       case 'say':
           //获取到客户端传过来的信息
           $text = $data['data'];
           $from_id = $data['from_id'];
           $to_id = $data['to_id'];
           //封装消息
           $info = array(
             'type'=>'text',
             'data'=>$text,
             'from_id'=>$from_id,
             'to_id'=>$to_id,
             'time'=>date('Y-m-d h:i:s',time()) 
           );
           Gateway::sendToUid($to_id,json_encode($info));
           return;
       //发送图片
       case 'img':
           $from_id = $data['from_id'];
           $to_id = $data['to_id'];
           $img = $data['img'];
           //封装消息
           $info = array(
             'type'=>'img',
             'data'=>$img,
             'from_id'=>$from_id,
             'to_id'=>$to_id,
             'time'=>date('Y-m-d h:i:s',time()) 
           );
           Gateway::sendToUid($to_id,json_encode($info));
           return;
     }
     //推送给指定的uid
     // 向所有人发送 
     // Gateway::sendToAll(json_encode($info));
}

can easily realize point-to-point message exchange.
