sorting doesn't sort?

[Håvard Olerud Eriksen]

I've got an array of arrays that I need to sort on preferably one of the
indices of the nested array, keeping the order of the outside array. The
structure is like this:

array([i] => array(key["name"] => data)
and what I need to do is to sort the nested array alphabetically according
to key["name"].
I can either use the name property of the nested array as index for the
outside array (then I need to keep the relationship between the outside
array and the nested array, or use a numeric index thus making the
relationship between the outside and nested array irrellevant.) What I need
to do in any case is to sort the nested array. I've tried using
arsort($array, SORT_STRING) but for some reason this doesn't sort the array
the way that I expected.

Can anyone help me out?

A var_dump of one element of the outside array looks like this:
array(2)
{ [1]=> array(2)
{ ["id"]=> string(1) "1" ["name"]=> string(6) "JustforSho w" }
{ [2]=> array(2)
{ ["id"]=> string(1) "1" ["name"]=> string(6) "Testing" }

etc.
