在PHP上排序数组

Question

So, I have this structure on an Array on PHP and I was wondering how to sort the values:

    Array
   (
       [0] => Array
       (
           [0] => One
           [1] => Ultra
           [2] => Plus
       )

       [1] => Array
       (
           [0] => Value
           [1] => Another value
       )

       [2] => Array
       (
           [0] => buzz
           [1] => fuzz
           [2] => bla
           [3] => bla
           [4] => blabla
       )
   )

I tried using array_multisort but it says: Message: array_multisort(): Array sizes are inconsistent

I expect every subarray sorted alphabetically. actual code:

array_multisort($array[0], SORT_ASC, SORT_STRING, $array[1], 
                           SORT_ASC, SORT_STRING, $array[2], 
                           SORT_ASC, SORT_STRING);

Answer 1

I solved it using a foreach:

for($i = 0; $i < sizeof($array);$i++)
{
  $low_array[$i ] = array_map('strtolower', $array[$i ]);
  array_multisort($array[$i], SORT_ASC, SORT_STRING, $array[$i]);
}

And this way the Warning doesn't show. :)
