Here is a solution if you want the Sundays in a specific date range.

function dateRange($begin, $end, $interval = null)
{
  $begin = new DateTime($begin);
  $end = new DateTime($end);

  $end = $end->modify('+1 day');
  $interval = new DateInterval($interval ? $interval : 'P1D');

  return iterator_to_array(new DatePeriod($begin, $interval, $end));
}

/* define date range */
$dates = dateRange('2018-03-01', '2018-03-31');

/* define weekdays */
$weekends = array_filter($dates, function ($date) {
  $day = $date->format("N");
  return $day === '6' || $day === '7';
});

/* weekdays output */
foreach ($weekends as $date) {
  echo $date->format("D Y-m-d") . "
";
}

/* define sundays */
$sundays = array_filter($dates, function ($date) {
  return $date->format("N") === '7';
});

/* sundays output */
foreach ($sundays as $date) {
echo $date->format("D Y-m-d") . "
";
}

/* define mondays */
$mondays = array_filter($dates, function ($date) {
 return $date->format("N") === '1';
});

/* mondays output */
foreach ($mondays as $date) {
echo $date->format("D Y-m-d") . "
";
}

Just change the number for any days you want in your output:

Monday = 1
Tuesday = 2
Wednesday = 3
Thursday = 4
Friday = 5
Saturday = 6
Sunday = 7
