我需要向连接到套接字服务器的客户端发送消息，但我需要它只发送给一个人，而不是这样的广播。我已经读过函数to（）的socket.IO，但我已经用几种方式实现了它，我没有得到它，我把它发送给所有人。这是我的代码
...

{
$socket->emit("new message", array(

"username" => $socket->username,
"action" => "chat",
"message" => [ "from" => $socket->username['WP_USER_DATA']['guid'], "type" => "", "time" => date('H:i'), "message" => $message ]
));
});

来自Socket.IO备忘单：
// sending to individual socketid (private message)
io.to(`${socketId}`).emit('hey', 'I just met you');
所以对你来说，这就像：
//I NEED HELP HERE, PLEASE
io->to($socketId)->emit("new message", array(
"username" => $socket->username,
"action" => "chat",
"message" => [ "from" => $socket->username['WP_USER_DATA']['guid'], "type" => "", "time" => date('H:i'), "message" => $message ]
));
注意：您需要存储（在数组中）id（$socket-
