How to show links to all categories of a product in the product page

[eu4ria]

Hello! In my vm 3.4.2 (php 7.1) site each product is getting into two categories. These two categories are equivalent. Category 1 - men or women and category 2 - original or copy.
How to show links to ALL categories in a product page?
Now in the product page there is a code:

Code Select Expand

<?php echo $this->category->category_name; ?>
This code shows only one category through which the visitor entered the page. and how to show also the second category?

on the product details template in the $this->product is an array of catids



   $this->product->categories => Array
        (
           

• => 181
              [1] => 183
          )
  
  or  $this->product->categoryItem is another array containing all cat info (name, id etc)
  
  just loop thru and render what info u want
