Laravel array_sort helper DESC e ASC

Question

I want to sort a multidimensionl array with one or more keys using the Laravel helper array_sort.

array(
    array('firstname_1','lastname_1'),
    array('firstname_2','lastnmae_2')
)

I want to order it first by name and then by name.

I also want to do this in DESC or ASC order. How can I achieve this?

There are functions on the Internet that can be implemented on the Internet, but I would like to understand how to use the Laravel helper. The document for array_sort ( http://laravel.com/docs/helpers#arrays ) I do not think is exhaustive.
