custom kick

so i have seen that on some huge networks when you get kicked , it doesn't say "Kicked by Admin:" how can i get this feature , how is it made?, does it use codes? or is it a edited PMMP version?

 

PHP:

$player->kick("This is your kick message", false)


The second parameter makes it so it doesn't display the "Kicked by admin. Reason: " message before the reason.

 

thanks
