The code use PHP POST method to call a function that will generate a random serial code looping the given strings using for() loop. 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/.

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="https://sourcecodester.com">Sourcecodester</a>
  11. 		</div>
  12. 	</nav>
  13. 	<div class="col-md-3"></div>
  14. 	<div class="col-md-6 well">
  15. 		<h3 class="text-primary">PHP - Generate Random Serial Code</h3>
  16. 		<hr style="border-top:1px dotted #ccc;"/>
  17. 		<div class="col-md-3">
  18. 			<form method="POST">				
  19. 				<center><button class="btn btn-info" name="create">Get Serial Code</button></center>
  20. 			</form>
  21. 		</div>
  22. 		<div class="col-md-6">
  23. 				<?php include 'get_serial.php'?>
  24. 		</div>
  25.  
  26. 	</div>
  27. </body>
  28. </html>

This code contains the main function of the application. This code will create a random serial code 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 get_serial.php 
  1. <?php
  2. 	function GetSerialCode() {
  3. 		$strings = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890';
  4. 		$stringLength = strlen($strings);
  5. 		$newStrings = '';
  6. 		for ($i = 0; $i < 8; $i++) {
  7. 			$newStrings .= $strings[rand(0, $stringLength - 1)];
  8. 		}
  9. 		return $newStrings;
  10. 	}
  11.  
  12. 	if(ISSET($_POST['create'])){
  13. 		echo '<div class="alert alert-info">MY SERIAL CODE</div>';
  14. 		echo '<center><h3 class="text-primary" style="background-color:#ccc; padding:10px;">'.GetSerialCode().'</h3></center>';
  15. 	}
