sorting an array dynamically without knowing existing dimensions

Question

I know that ksort() is used to sort array by keys. The max dimension of my array always differs. Sometime 2, sometimes 5, sometime 10 dimensional so how do I use ksort() to do sorting dynamically without knowing how many dimensions exist in it?

Thanks

EXAMPLE ARRAY

[2010] => Array
        (
            [3] => Array
                (
                    [B] => Array
                        (
                            [6] => Array
                                (
                                    [Patato] => 
                                )

                            [C] => Array
                                (
                                    [Patato] => 
                                    [Zozo] => 
                                )
                        )

                    [A] => Array
                        (
                            [F] => Array
                                (
                                    [Tomato] => 
                                    [Apple] => 
                                    [Kiwi] => 
                                )
                        )

            [1] => Array
                (
                    [4] => Array
                        (
                            [A] => Array
                                (
                                    [Orange] => 
                                )
                        )

Can you post contents of a sample array and the sort criteria? — Salman A, Nov 13 '12 at 12:04
Sorting an array by the keys of its value is independant from deeper nesting levels of the values ('dimension'). — arkascha, Nov 13 '12 at 12:05

If you mean you want to sort recursive:

function deep_ksort(&$arr) {
    ksort($arr);
    foreach ($arr as &$a) {
        if (is_array($a) && !empty($a)) {
            deep_ksort($a);
        }
    }
}

This comes from http://www.php.net/manual/en/function.ksort.php#105399
