In this tutorial we will create a Sorting Array Key using PHP. This code will sort array value when user select the proper order in the table. The code use PHP POST method that call a specific functions in order to sort the array value using array_multisort by setting the parameter with array index position and array order type. 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 https://www.apachefriends.org/index.html.

And, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

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-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="https://sourcecodester.com">Sourcecodester</a>
  11. " rel="nofollow">https://sourcecodester.com">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 - Sorting Array Key</h3>
  17. <hr style="border-top:1px dotted #ccc;"/>
  18. <form method="POST" action="">
  19. <div class="form-inline">
  20. <select name="key" required="required" class="form-control">
  21. <option value="sort_asc">Ascending</option>
  22. <option value="sort_desc">Descending</option>
  23. </select>
  24. <button name="sort" class="btn btn-primary">Sort</button>
  25. <div>
  26. </form>
  27. <br />
  28. <div class="col-md-6">
  29. <table class="table table-bordered">
  30. <thead class="alert-info">
  31. <tr>
  32. <th>Member Name</th>
  33. <th>Address</th>
  34. </tr>
  35. </thead>
  36. <tbody>
  37. <?php include 'sort.php'?>
  38. </tbody>
  39. </table>
  40. </div>
  41. </div>
  42. </body>
  43. </html>

Creating the Main Function

This code contains the main function of the application. This code will sort array value 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 sort.php

  1. <?php
  2. $members = array(
  3. array("name" => "Tony Stark", "address" => "Japan"),
  4. array("name" => "Peter Piper", "address" => "New York"),
  5. array("name" => "Carl Roger", "address" => "London"),
  6. array("name" => "Isko Sky", "address" => "England"),
  7. array("name" => "Zia Adantos", "address" => "Egypt")
  8. );
  9.  
  10. if(ISSET($_POST['sort'])){
  11. $sortKey = array();
  12. $sort = $_POST['key'];
  13. foreach($members as $member){
  14. foreach($member as $key=>$value){
  15. if(!isset($sortKey[$key])){
  16. $sortKey[$key] = array();
  17. }
  18. $sortKey[$key][] = $value;
  19. }
  20. }
  21.  
  22. $sortby = "name";
  23.  
  24. if($sort == "sort_asc"){
  25. array_multisort($sortKey[$sortby],SORT_ASC,$members);
  26. }else if($sort == "sort_desc"){
  27. array_multisort($sortKey[$sortby],SORT_DESC,$members);
  28. }
  29.  
  30. foreach($members as $key => $values){
  31. ?>
  32. <tr>
  33. <td><?php echo $values['name']?></td>
  34. <td><?php echo $values['address']?></td>
  35. </tr>
  36. <?php
  37. }
  38. }else{
  39. foreach($members as $key => $values){
  40.  
  41. ?>
  42. <tr>
  43. <td><?php echo $values['name']?></td>
  44. <td><?php echo $values['address']?></td>
  45. </tr>
  46. <?php
  47. }
  48. }
  49. ?>
