Solved Human nps

Hi, I would like to create TOP-list on my server.
But text is very simply. And I think about nps-top:
Human nps have a skin a top player and player's name.
And when anyone tap on nps, we send him best score and info about top-player
How can I create nps, how can I change skin?

PHP:

$npc = new Human($player->chunk,
new CompoundTag("", [
"Pos" => new ListTag("Pos", [
new DoubleTag("", $block->getX() + 0.5),
new DoubleTag("", $block->getY()),
new DoubleTag("", $block->getZ() + 0.5)
]),
"Motion" => new ListTag("Motion", [
new DoubleTag("", 0),
new DoubleTag("", 0),
new DoubleTag("", 0)
]),
"Rotation" => new ListTag("Rotation", [
new FloatTag("", $player->getYaw()),
new FloatTag("", $player->getPitch())
]),
"Skin" => new CompoundTag("Skin", [
"Data" => new StringTag("Data", $player->getSkinData())
])
]
));
$npc->spawnToAll();
$npc->setDataProperty(Entity::DATA_NAMETAG, Entity::DATA_TYPE_STRING, $player->getName());
$npc->setDataProperty(Entity::DATA_SHOW_NAMETAG, Entity::DATA_TYPE_BYTE, 1);

$npc->setSkin($skin, $skinname);
