Help sorting this array

Array
(
    [0] => Array
        (
            [13] => Array
                (
                    [0] => Suzukis release a new bike yada
                    [1] => 6
                )

        )

    [1] => Array
        (
            [1] => Array
                (
                    [0] => Test Title
                    [1] => 8
                )

        )

    [2] => Array
        (
            [2] => Array
                (
                    [0] => BiZ article testing
                    [1] => 19
                )

        )

    [3] => Array
        (
            [2] => Array
                (
                    [0] => biz starboyz test234
                    [1] => 20
                )

        )

    [4] => Array
        (
            [2] => Array
                (
                    [0] => Beat the Winter Bugs - Cold and Flu
                    [1] => 22
                )

        )

    [5] => Array
        (
            [1] => Array
                (
                    [0] => Test Name
                    [1] => 26
                )

        )

    [6] => Array
        (
            [2] => Array
                (
                    [0] => Another test
                    [1] => 27
                )

        )

)

Is it possible to sort this array by the second key down instead of the first. I.e. the keys which contain the values 13, 1, 2, 2, 2, 1, 2

PHP Code:

function cmp($a, $b) {
  $keys_a = array_keys($a);
  $keys_b = array_keys($b);
  if ($keys_a[0] == $keys_b[0]) return 0;
  return ($keys_a[0] < $keys_b[0]) ? -1 : 1;
}

usort($array, 'cmp'); 


Smth. like this might work.

No luck Kirby

Hmm, running this code gives me

Array
(
    [0] => Array
        (
            [1] => Array
                (
                    [0] => Test Title
                    [1] => 8
                )

        )

    [1] => Array
        (
            [2] => Array
                (
                    [0] => Another test
                    [1] => 27
                )

        )

    [2] => Array
        (
            [2] => Array
                (
                    [0] => Beat the Winter Bugs - Cold and Flu
                    [1] => 22
                )

        )

    [3] => Array
        (
            [2] => Array
                (
                    [0] => BiZ article testing
                    [1] => 19
                )

        )

    [4] => Array
        (
            [2] => Array
                (
                    [0] => biz starboyz test234
                    [1] => 20
                )

        )

    [5] => Array
        (
            [13] => Array
                (
                    [0] => Suzukis release a new bike yada
                    [1] => 6
                )

        )

)

Isn't that what you want?

[Dean C]

Yeah but it didn't work when I did. I've just changed my code anyway, thanks for the help Kirby
