How to get the path specified in the breadcrumb?

Question

1C-Bitrix

You need to get the path indicated in the breadcrumb, but the product has several categories in Bitrix, so it was not possible to understand which of the categories is the main one. How can you get it?

Answer 1

In Bitrix there is no concept of the main category or not the main one, there are nesting levels.
If the chain is formed, then you can get an array of elements from$APPLICATION->arAdditionalChain
