run command as player or console

PHP:

        case 9:
            if($sender->hasPermission("coreui.pl")) {
            $command = "pl" ;
            $this->getServer()->getCommandMap()->dispatch($sender, $command);
             return true;
               }else{
                   $sender->sendMessage("§cУ вас недостаточно прав для использования этой команды");
                   return true;
               }
        break;
