Send message to specific connected user or to all connected users

[colomarco]

I know that is not an issue and I'm sorry but I don't know where to write.
All works great, but I don't understand how is possible to send a specific message to a desired user or to all connected users. Is it possible to have few examples about that??
Thank you so much!

Hi,

In echoserver example file "testwebsock.php"

  protected function process ($from, $message) { // changed $user to $from, just to avoid confusion
	foreach ($this->users as $user){ // sending to all connected users
		if($from !== $user){ // avoid to send msg to sender
			$this->send($user, $message);
		}
	}
  }

How can i send to specific user connected to socket?

[oguls]

Your all connected users are in this object/array $user, try to print_all to check how this array structure looks like.

To send to specific user you need to know the id of user like $user[id] then
$this->send($user[id], $message)

@oguls thank you very much.
It might be out of discussion to ask, but is it possible to call send function inside codeigniter controller ?
Javascript:
socket.send('message');
Php :
any equivalent of js sample in php ?

Thank you very much!!!
