Solved How do you put armor on a player?

How can I equip a chest plate or another piece of armor on a player?

PHP:

 $player->getInventory()->setArmorContents([Item::get(298),Item::get(299),Item::get(300),Item::get(301)]);

Oh ok, thanks

no problem ^^ <3

Also you can set them separetely:

PHP:

$player->getInventory()->setHelmet(Item::get(298));
$player->getInventory()->setChestplate(Item::get(299));
$player->getInventory()->setLeggings(Item::get(300));
$player->getInventory()->setBoots(Item::get(301));
