  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1" />
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
  6. </head>
  7. <body>
  8. <nav class="navbar navbar-default">
  9. <div class="container-fluid">
  10. <a class="navbar-brand" href="<a href="">Sourcecodester</a>
  11. " rel="nofollow">">Sourcecodester</a>
  12. </a> </div>
  13. </nav>
  14. <div class="col-md-3"></div>
  15. <div class="col-md-6 well">
  16. <h3 class="text-primary">PHP - Calculating Remaining Days In A Month</h3>
  17. <hr style="border-top:1px dotted #ccc;"/>
  19. <div class="col-md-3"></div>
  20. <div class="col-md-6">

  24. <input type="date" name="date" class="form-control"/>
  25. </div>
  26. <center><button class="btn btn-primary" name="calculate">Calculate</button></center>
  27. </form>
  28. <?php include 'calculate.php'?>
  29. </div>
  30. </div>
  31. </body>
  32. </html>

Creating the Main Function

This code contains the main function of the application. This code will get the remaining days 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 calculate.php

  1. <?php
  2. if(ISSET($_POST['calculate'])){
  3. $month=date("m", strtotime($_POST['date']));
  4. $day=date("d", strtotime($_POST['date']));
  5. $year=date("Y", strtotime($_POST['date']));
  7. $date=$year."-".$month."-".$day;
  9. $timestamp = strtotime($date);
  11. $remainingDays = (int)date('t', $timestamp) - (int)date('j', $timestamp);
  13. echo "<center><h3>There are <span class='text-primary'>".$remainingDays."</span> days remaining</h3></center>";
