You need to iterate using three for loops and lookup in given day, month and year. If the day, month and year is available, then put them into a variable.

<?php
$givenDate = '2018-04-28';
$fiveYears  = '2018,2019,2020,2021,2022';  
$fiveMonths = '03,05,07,08,09';
$fiveDays   = '25,26,27,28,29';
$fYears = explode(',', $fiveYears);
$fMonths = explode(',', $fiveMonths);
$fDays = explode(',', $fiveDays);
$nextDate = null;
foreach($fYears as $yr) {
   foreach($fMonths as $mn) {
      foreach($fDays as $dy) {
         $t = $yr.'-'.$mn.'-'.$dy;
            if($t > $givenDate) {
               $nextDate = $t;
               break 3;
            }
      }
   }
}
if($nextDate) {
   echo 'The next date value is =' . $nextDate;
}
else {
   echo 'No date is found.';
}
?>
