In this tutorial we will create a Generate Random Serial Code using PHP. This code will generate a random serial code when the user click thebutton. 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/.

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.

<!DOCTYPE html>
<html lang="en">
        <head>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1" />
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">PHP - Generate Random Serial Code</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-3">
                        <form method="POST">                            
                                <center><button class="btn btn-info" name="create">Get Serial Code</button></center>
                        </form>
                </div>
                <div class="col-md-6">
                                <?php include 'get_serial.php'?>
                </div>
                
        </div>
</body>
</html>

Creating the Main Function

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

<?php
        function GetSerialCode() {
                $strings = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890';
                $stringLength = strlen($strings);
                $newStrings = '';
                for ($i = 0; $i < 8; $i++) {
                        $newStrings .= $strings[rand(0, $stringLength - 1)];
                }
                return $newStrings;
        }
        
        if(ISSET($_POST['create'])){
                echo '<div class="alert alert-info">MY SERIAL CODE</div>';
                echo '<center><h3 class="text-primary" style="background-color:#ccc; padding:10px;">'.GetSerialCode().'</h3></center>';
        }
        
?>
