How to transfer a player to another server

How can I transfer a player to a server?

 

Player::transfert(ip, port)

 

thank mate

 

PHP:

$player->transfer($address, $port, $message);

$player is an instance of \pocketmine\Player (the player to be transferred)
$address is a string (the IP or domain of the server)
optional $port is an int (the port of the server)
optional $message is a string (kick message to use)

 

How can you set a message like a loading screen message?

So the third parameter of transfer() is a string...?
