How to Create a Chatbot using PHP, Ajax, Jquery

Today in this blog you'll learn how to create a Simple Chatbot using PHP with MySQL & jQuery (Ajax).

A chatbot is a computer program designed to simulate human conversation. These chatbots reply to you instantly according to your queries because programmers have inserted thousands of inputs/replies/queries into the database that can be asked by the user. To make an advanced chatbot we've to code more and more but I tried to make a simple chatbot with few lines of codes and queries which help you to get an idea about how a chatbot actually works.

Dp.php

<?php $host = "localhost"; $user = "root"; $pass = "root"; $db_name = "chat"; $con = new mysqli($host, $user, $pass, $db_name); ?>

Index.php

<?php include 'db.php'; ?>

<!DOCTYPE html>

<html>

               <head>

                               <title>My Chat App</title>

                               <link rel="stylesheet" href="style.css" media="all" />

               </head>

               <body>

                               <div id="container">

                                              <div id="chat_box">

                                                             <?php include 'db.php';

                                                             $query = "SELECT * FROM chat ORDER BY id";

                                                             $run = $con->query($query);

                                                             while($row = $run->fetch_array()) : ?>

                                                             <div id="chat_data">

                                                                            <span style="color:green;"><?php echo $row['name']; ?> : </span>

                                                                            <span style="color:brown;"><?php echo $row['msg']; ?></span>

                                                                            <span style="float:right;"><?php echo $row['date']; ?></span>

                                                                            </div>

                                                             <?php endwhile; ?>

                                              </div>

                                              <form method="post" action="index.php">

                                                             <input type="text" name="name" placeholder="Enter Name: " />

                                                             <textarea name="enter message" placeholder="Enter Message"></textarea>

                                                             <input type="submit" name="submit" value="Send!" />

                                              </form>

                               </div>

                               <?php if(isset($_POST['submit'])){ $name = $_POST['name']; $msg = $_POST['enter_message']; $query = "INSERT INTO chat (name,msg) VALUES ('$name','$msg')"; $run = $con->query($query); } ?>

               </body>

</html>

<script> function chat_ajax(){ var req = new XMLHttpRequest(); req.onreadystatechange = function() { if(req.readyState == 4 &&req.status == 200){ document.getElementById('chat').innerHTML = req.responseText; } } req.open('GET', 'chat.php', true); req.send(); } setInterval(function(){chat_ajax()}, 1000) </script>

Style.css

*{ padding: 0; margin: 0; border: 0; }
 body{ background: silver; } 
#container{ width: 40%; background: white; margin: 0 auto; padding: 20px; }
