Question : PHP - Modify foreach to display message if 0 iterations

Hi,
I have a code snippet from magento shopping cart.

This foreach loop iterates through the product categories and displays them in a list.

If no categories exist I want to display a message "No categories available"

How could I do this on the current snippet?

Regards
Mitch
