Zend framework 2 validate date

How do I validate if the date is valid in this format? Y-m

For an instance, date is 2016-00, this should return as invalid as there is no such month of 00.

2016-01 should return as valid since 01 represents as January.

I tried using Date::createFromFormat('Y-m', '2016-00') but it returns this:

object(DateTime)[682]
  public 'date' => string '2015-12-25 06:07:43' (length=19)
  public 'timezone_type' => int 3
  public 'timezone' => string 'Antarctica/Casey' (length=16)

in which it considers it as a valid date.

This is a workaround but I suppose it works. You can use this function:

function validateDate($date, $format)
{
    $dateTime = \DateTime::createFromFormat($format, $date);// create a DateTime object of the given $date in the given $format
    return $dateTime && $dateTime->format($format) === $date;// returns true when the conversion to DateTime succeeds and formatting the object to the input format results in the same date as the input
}

var_dump(validateDate('2016-00', 'Y-m'));// returns false
var_dump(validateDate('2016-01', 'Y-m'));// returns true

function was copied from this answer or php.net

In your case it would return false as $dateTime->format($format) == $date would return false.

Hope this helps.
