  26. for($i = 1; $i<=12; $i++){
  27. echo "<option value='".$i."'>".$months[$i - 1]."</option>";
  28. }
  29. ?>
  30. </select>
  31. </div>
  32. <div class="form-group">

  36. <?php
  37. $year = date("Y", strtotime("+8 HOURS"));
  38. for($y = $year; $y>=1965; $y--){
  39. echo "<option value='".$y."'>".$y."</option>";
  40. }

This code contains the main function of the application. This code will get the total days in a month when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as get_total_days.php

  1. <?php
  2. if(ISSET($_POST['get'])){
  3. $month = $_POST['month'];
  4. $year = $_POST['year'];
  5. $months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];
  6. $calculate = cal_days_in_month(CAL_GREGORIAN,$month,$year);
  7. echo "<center><h2>Total of <span class='text-danger'>".$calculate."</span> days in <span class='text-success'>".$months[$month - 1]." ".$year."</span><h2></center>";
