command arg isn't working?

i have this onCommand function but when i do /price <player> it just returns the sender price

PHP:

    public function onCommand(CommandSender $sender, Command $cmd, $label, array $param){
        if(strtolower($cmd->getName()) === "price"){
            if(isset($args[0])){
                $target = $this->getServer()->getPlayer($args[0]);
                if($target !== null && $target->isOnline()){
                    $sender->sendMessage("§l§c  TheVortex §7>> §r§e ".$target->getName()." §7 is worth §l§a$ §r§f§a".$this->getWorth($target));
                } else {
                    $sender->sendMessage("§l§c  TheVortex §7>> §r§4 ".$target->getName()." Isnt online!");
                }
            } else {
                $sender->sendMessage("§l§c  TheVortex §7>> §r§§§7Your head is worth §l§a$ §r§f§a".$this->getWorth($sender));
            }
        }
    }
}

 

huh u made array $param not $args

 

PHP:

 public function onCommand(CommandSender $sender, Command $cmd, $label, array $param){
        if(strtolower($cmd->getName()) === "price"){
            if(isset($param[0])){
                $target = $this->getServer()->getPlayer($param[0]);
                if($target !== null && $target->isOnline()){
                    $sender->sendMessage("§l§c  TheVortex §7>> §r§e ".$target->getName()." §7 is worth §l§a$ §r§f§a".$this->getWorth($target));
                } else {
                    $sender->sendMessage("§l§c  TheVortex §7>> §r§4 ".$target->getName()." Isnt online!");
                }
            } else {
                $sender->sendMessage("§l§c  TheVortex §7>> §r§§§7Your head is worth §l§a$ §r§f§a".$this->getWorth($sender));
            }
        }
    }
