You need to pass a second and third array to array_map() with the same number 
of elements as the first array. The arguments to the callback function are the 
elements from each array at the same offset.

Something like $clean = array_map('mb_convert_encoding', $dirty_arr, 
array_fill(0, count($dirty_arr), 'utf-16'), array_fill(0, count($dirty_arr),
