Ban Client

PHP:

                if(($player = $this->getServer()->getPlayer($args[0])) instanceof Player) {
                    $name = $player->getName();
                    $id = $player->getUniqueId();
                    $banned = $this->getConfig()->get("Banned", []);
                    $times = $this->getConfig()->get("Times", []);
                    $banned[$name] = $cid;
                    $times[$cid] = -1;
                    $this->getConfig()->set("Banned", $banned);
                    $this->getConfig()->set("Times", $times);
                    $this->getConfig()->save();
                    $player->setBanned(true); //easy way to kick the player while giving a ban message
                    $sender->sendMessage($name." is now banned with the cid: ".$cid);
                }else{
                    $sender->sendMessage("That player isn't online right now!");
