In this tutorial we will create a Simple Update Time using PHP. This code will update time when the user click the update button. The code use PHP POST method to initiate a query that set the value into a date function as parameter to add time. This is a user-friendly kind of program feel free to modify it.

We will be using PHP as a scripting language and interpreter that is used primarily on any webserver including xamp, wamp, etc. It is being use to any famous websites and it has a modern technology that can easily be use by the next generation.

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server

And, this is the link for the bootstrap that i used for the layout design

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-widht, 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 - Simple Update Time</h3>
  17. <hr style="border-top:1px dotted #ccc;"/>
  18. <div class="col-md-2"></div>
  19. <div class="col-md-8">
  20. <?php
  21. $date = date("M d, Y h:i:s A");
  22. echo "<h4>Current Time: ".$date."</h4>";
  23. ?>
  24. <form action="" method="POST">
  25. <div class="form-inline">
  26. <input type="number" class="form-control" min="0" name="amount">
  27. <select name="type" class="form-control">
  28. <option value="seconds">Seconds</option>
  29. <option value="minutes">Minutes</option>
  30. <option value="hours">Hours</option>
  31. <option value="days">Days</option>
  32. <option value="months">Months</option>
  33. <option value="years">Years</option>
  34. </select>
  35. <button class="btn btn-warning" name="update">Update</button>
  36. </div>
  37. </form>
  38. <?php include'update_time.php'?>
  39. </div>
  40. </div>
  41. </body>
  42. </html>

Creating the Main Function

This code contains the main function of the application. This code will update time 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 update_time.php

  1. <?php
  2. if (isset($_POST['update'])){
  3. $amount=$_POST['amount'];
  4. $type=$_POST['type'];
  5. echo "<h5>You added <strong>".$amount."</strong> ".$type.".</h5>";
  6. $newdate=date('M d, Y h:i:s A', strtotime("+$amount $type", strtotime($date)));
  7. echo "<h4> Your New Datetime: <span class='text-primary'>".$newdate."</span></h4>";
  8. }
  10. ?>
