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 - Create Random Characters</h3>
  17. <hr style="border-top:1px dotted #ccc;"/>
  18. <div class="col-md-3">
  19. <form method = "POST">
  20. <div class="form-group">
  21. <label>Enter some length</label>
  22. <input type="number" min="1" max="20" name="length" class="form-control" require="required"/>

  25. <center><button class="btn btn-info" name="create"><span class="glyphicon glyphicon-random"></span> Create Char</button></center>
  26. </form>
  27. </div>
  28. <div class="col-md-6">
  29. <?php include 'character.php'?>
  30. </div>
  31.  
  32. </div>
  33. </body>
  34. </html>

Creating the Main Function

This code contains the main function of the application. This code will create a random characters 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 character.php

  1. <?php
  2. if(ISSET($_POST['create'])){
  3. $length = $_POST['length'];
  4. echo '<center><h3 class="text-primary">'.GenerateChar($length).'</h3></center>';
  5. }
  6.  
  7. function GenerateChar($length) {
  8. $strings = '[email protected]#$%^&*()_+';
  9. $stringLength = strlen($strings);
  10. $newStrings = '';
  11. for ($i = 0; $i < $length; $i++) {
  12. $newStrings .= $strings[rand(0, $stringLength - 1)];
  13. }
  14. return $newStrings;
  15. }
  16.  
  17. ?>
