Just a quick note to let people know that shuffle() will work on multidimensional associative arrays
provided that the first key is already numeric.
So this array can be shuffled without losing any of the secondary keys or their values:
$array[0]['color'], $array[0]['size'], $array[0]['fabric']
. . .
$array[50]['color'], $array[50]['size'], $array[50]['fabric']
I recently ran up against needing to randomize this array and tried shuffle even though it's
not really for associative arrays.
Hope it helps somebody out there.
