Answer 1

use array_filter()

example:

$result = array_filter($array);

array_filter() remove empty array elements from array.

Answer 2

based on this answer:

$month=array_filter($month);

if you did not provide a callback for array_filter, all entries of array equal to FALSE or Null will be removed
