Sorting a multi-dimentsional associative array of arrays

Like the title sais I have no idea where to start and using asort() and sort() are not helping in the way I thought it would. Essentially I have an array as such:

$array = array(
    'array_c' => array(
        'array_b' => (
            array('object' => 'e some Object'),
            array('object' => 'b some Object'),
        ),
        'array_a' => (
            array('object' => 'awesome Object'),
        ),
    ),
    'array_a' => array(
        'array_e' => (
            array('object' => 'e some Object'),
        ),
        'array_a' => (
            array('object' => 'b awesome Object'),
        );
    );
);

So I was looking at asort as I want to keep the associations the same, The function I have started writing is:

function sort_me(some_array){
    $new_array = asort(some_array);
    return $new_array;
}

this function then takes in $array['array_c'] so that you get back an alphabetically sorted array that looks like:

    'array_c' => array(
        'array_a' => (
            array('object' => 'awesome Object'),
        ),
        'array_b' => (
            array('object' => 'b some Object'),
            array('object' => 'e some Object'),
        ),

    ),

can some one tell me why my function is not working? Am I misunderstanding the power of asort?

ksort is the way to go, but ksort does not return a newly sorted array:

http://us.php.net/ksort

it returns a bool -> true if the array could be sorted, otherwise false...

this code snipped should do what you need:

ksort($array);
foreach($array as $key=>$value){
    ksort(value);
    $array[$key]=$value;
}
print_r($array);
