PHP multi-dimension array sorting

Anon

I am trying to sort an array that is dynamically built.

The array looks like this:
$user_info["points"][$user_index] = 6;
$user_info["name"][$user_index] = "joe";
$user_info["account"][$user_index] = 54785;
$user_info["game1"][$user_index] = "buffalo";
$user_info["game2"][$user_index] = "newyork";
$user_info["game3"][$user_index] = "miami";
.
.
.
$user_info["gameX"][$user_index] = "x";

this array has an $user_index for each user.
I currently have 5 users....ie. 5 indicies.

I am trying to sort this associative based on points.

I am using the following function:
array_multisort ($user_info["points"], SORT_DESC, array_keys($user_info) );

but i am getting the message:
Warning: Array sizes are inconsistent in C:\Inetpub\wwwroot\Football_Pool\opponents_weekly_picks.php on line 115

I am able to sort only the "points" column by using:
array_multisort ($user_info["points"], SORT_DESC);

but cannot sort the entire array sucessfully.
You see the array columns are dynamic....ie. X (the number of games change from week to week) so I cannon simply use the following sort:
array_multisort ($user_info["points"], SORT_DESC, $user_info["name"][$user_index], $user_info["account"][$user_index], $user_info["game1"][$user_index], $user_info["game2"][$user_index], $user_info["game3"][$user_index],....$user_info["gameX"][$user_index]);

Because I do not know what X is....PLEASE HELP.

THANKS IN ADVANCE.

hi,

1: first of all, the way you use arrays is really not healthy,
the INDEX of a 2 dimensional array should be the 'in' the first bracket...

NOT:
$u_info["name"][$user_index] = "BLA";
$u_info["surname"][$user_index] = "BLA";

but:
$u_info[$user_index][name] = "BLA";
$u_info[$user_index][surname] = "BLA";

but this is not what php complains about..
php complains about the way you use indexes, i dont like indexes so i dont use them but you should write something like
5 => "second" or similar, thats what i've understood... but i still dont like them and i wouldn't recommend them... 'cause i dont like 'em..
