PHP Array - Removing empty values

Question

How do I loop through this array and remove any empty values:

[28] => Array
    (
        [Ivory] => 
        [White] => 
    )

[29] => Array

I see you already have a working solution, but just for fun, with array_map goodness:

$array = array_filter(array_map('array_filter', $array));
