Create a function to return the closest date from today, where the array of dates is: $dates = array("2022-10-03 19:30:00","2022-11-22 19:30:00","2023-01-25 19:30:00","2023-02-11 18:00:00","2023-04-09 13:00:00","2023-04-15 13:00:00","2023-04-17 19:30:00","2023-04-20 19:30:00","2023-04-22 13:00:00","2023-04-24 12:00:00","2023-04-27 12:00:00","2023-04-29 12:00:00");

function getClosestDate($dateArray) {
  $today = new DateTime();
  $closest = null;
  foreach ($dateArray as $date) {
    $newDate = new DateTime($date);
    if ($closest == null || abs(($today - $newDate)) < ($today - $closest)) {
      $closest = $newDate;
    }
  }
  return $closest;
}
