Sort a multi-dimensional array by the size of its sub-arrays

Question

I have this multidimensional array:

Array
(
    [0] => Array
        (
        [0] => 2012-02-26 07:15:00
        )
    [1] => Array
        (
              


        

Answer 1

This might be what you seek:

natsort($sub_count);
$rev = array_reverse($sub_count);
$result = array_pad($rev, 3);

You might want to omit the actual sorting if the values you have are already in order.
