Get first key in a [possibly] associative array?

I have this array:

Array
(
    ['foobar'] => Array
        (
            [key1] => value1
            [key2] => value2
        )

)

I want to get to name of the first index (foobar). How can I do it?

Assuming that you haven’t used each(), next(), prev() or in any other manner have you advanced the array pointer:

key($array);
