Removing items will names

hey , how can i remove an item with a custom name? heres my code i was using but it deletes the entire stack of items , i only want one to get removed from the entire stack.

PHP:

                         foreach($player->getInventory()->getContents() as $item) {
                  if($item->getId() === 340 and $item->getCustomName() === "CrateKey") {
                  $item->setCount(1);
                  $player->getInventory()->removeItem($item);

 

PHP:

if($item->getId() === 340 and $item->getCustomName() === "CrateKey") $item->setCount($item->getCount() - 1);

 

thx , just to save time , how can i create an array like $names = [1 => "name", 2 => "name"]; then make it were the number is the id(1 for example) and the following is the item names.

 

Code:

$arr[1] = "string"
