  9. <div class="container-fluid">
  10. <a class="navbar-brand" href="">Sourcecodester</a>
  11. </div>
  12. </nav>
  13. <div class="col-md-3"></div>

  29. </body>
  30. <script src="js/jquery-3.2.1.min.js"></script>
  31. <script src="js/script.js"></script>
  32. </html>

Creating the Main Function

This code contains the main function of the application. This code will delete duplicate array object 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 shown below.

  1. <?php
  2. $array = array("Ferrari", "Suzuki", "Mustang", "Suzuki", "Ferrari");
  3. if(ISSET($_POST['res'])){
  4. echo "<pre>";
  5. print_r($array);
  6. echo "</pre>";
  7. }
  9. ?>


  1. <?php
  2. $array = array("Ferrari", "Suzuki", "Mustang", "Suzuki", "Ferrari");
  3. if(ISSET($_POST['res'])){
  4. $result = array_unique($array);
  5. echo "<pre>";
  6. print_r($result);
  7. echo "</pre>";
  8. }
  10. ?>

  1. $(document).ready(function(){
  3. displayData();
  5. function displayData(){
  6. $.ajax({
  7. url: "data.php",
  8. type: "POST",
  9. data: {res: 1},
  10. success: function(data){
  11. $('#result').html(data);
  12. }
  13. });
  14. }
  16. $('#delete').on('click', function(){
  17. $.ajax({
  18. url: "delete.php",
  19. type: "POST",
  20. data: {res: 1},
  21. success: function(data){
  22. $('#result').html("<center><h4>Clearing duplicate objects...</h4></center>");
  23. $('#delete').attr('disabled', 'disabled');
