Here's another way to do it. Each function will return either 4 or 5. If you
need both Saturdays and Sundays, just call both functions:

<?

function get_saturdays($month, $year) {

  $sat = 4;

// time stamp of noon on the first day of the month
  $first_day = mktime(12, 0, 0, $month, 1, $year);

  switch ($month) {
    case 1:
    case 3:
    case 5:
    case 7:
    case 8:
    case 10:
    case 12:
      if (date("w", $first_day) > 3) {
 $sat++;
      }
      break;
    case 2:
      if ((date("L", $first_day) == 1) && (date("w", $first_day) > 5)) {
 $sat++;
      }
      break;
    case 4:
    case 6:
    case 9:
    case 11:
      if (date("w", $first_day) > 4) {
 $sat++;
      }
      break;
  }

  return($sat);

}

function get_sundays($month, $year) {

  $sun = 4;

// time stamp of noon on the last day of the month
  $last_day = mktime(12, 0, 0, $month, date("t", $first_day), $year);

  switch ($month) {
    case 1:
    case 3:
    case 5:
    case 7:
    case 8:
    case 10:
    case 12:
      if (date("w", $last_day) < 3) {
 $sat++;
      }
      break;
    case 2:
      if ((date("L", $last_day) == 1) && (date("w", $last_day) < 1)) {
 $sat++;
      }
      break;
    case 4:
    case 6:
    case 9:
    case 11:
      if (date("w", $last_day) < 2) {
 $sat++;
      }
      break;
  }

  return($sun);

}

?>
