Real-time Chat Application with Bootstrap 5 & PHP Socket Programming Tutorial

Building a Real-time Chat Application with Bootstrap 5 and Socket Programming

Creating a chat application involves integrating real-time data transfer between a client and a server. By combining Bootstrap 5 for the frontend and PHP Socket Programming for real-time communication, we can create an engaging, responsive chat interface. This guide will cover setting up the UI, configuring the backend socket server, and connecting both to enable real-time messaging.

What You’ll Need

Bootstrap 5 – Provides a modern, responsive UI design.
PHP Socket Programming – Enables the real-time data exchange between client and server.
JavaScript and jQuery – To manage client-side interactivity.
PHP – For server-side logic and socket handling.

Key Features of Our Chat Application

Real-time Messaging: Messages appear instantly for all users.
Responsive Design: Bootstrap 5 makes the application accessible across devices.
User-friendly Interface: A clean, modern chat window that is easy to use.

Step 1: Setting Up the Bootstrap 5 Frontend

The frontend chat interface will be built with Bootstrap 5. Here’s how to create a simple chat window.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Real-time Chat Application</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css" rel="stylesheet">
    <style>
        #chat-box {
            height: 400px;
            overflow-y: scroll;
            border: 1px solid #ddd;
            padding: 15px;
            background-color: #f9f9f9;
        }
    </style>
</head>
<body>
    <div class="container mt-5">
        <h3 class="text-center">Real-time Chat Application</h3>
        <div id="chat-box" class="mb-3"></div>
        <div class="input-group">
            <input type="text" id="message" class="form-control" placeholder="Type your message...">
            <button id="send" class="btn btn-primary">Send</button>
        </div>
    </div>

    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script src="chat.js"></script>
</body>
</html>

In this HTML layout:

The #chat-box div is where chat messages will appear.
The input field and button allow users to type and send messages.
We use Bootstrap classes for styling and responsiveness.

Step 2: Setting Up the PHP Socket Server

Now, let’s create the PHP socket server that listens for incoming messages, broadcasts them to connected clients, and ensures real-time updates.

<?php
$host = '127.0.0.1';
$port = 8080;

// Create a TCP Stream socket
$serverSocket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_bind($serverSocket, $host, $port);
socket_listen($serverSocket);

$clients = [];

while (true) {
    $read = array_merge([$serverSocket], $clients);
    socket_select($read, $write, $except, 0);

    if (in_array($serverSocket, $read)) {
        $clientSocket = socket_accept($serverSocket);
        $clients[] = $clientSocket;
    }

    foreach ($clients as $key => $clientSocket) {
        if (in_array($clientSocket, $read)) {
            $message = socket_read($clientSocket, 1024);
            if ($message === false) {
                unset($clients[$key]);
                socket_close($clientSocket);
                continue;
            }
            foreach ($clients as $broadcastSocket) {
                socket_write($broadcastSocket, $message, strlen($message));
            }
        }
    }
}
?>

This server script:

Creates a TCP socket and listens for incoming connections.
Accepts multiple clients and reads messages.
Broadcasts each incoming message to all connected clients, enabling real-time updates.

Step 3: Writing the Client-side JavaScript for Real-time Messaging

To send and receive messages, we’ll use JavaScript (and jQuery) to handle socket communication and display messages in the UI.

Create a new file named chat.js:

$(document).ready(function() {
    const ws = new WebSocket('ws://127.0.0.1:8080');

    ws.onmessage = function(event) {
        $('#chat-box').append('<p>' + event.data + '</p>');
    };

    $('#send').click(function() {
        const message = $('#message').val();
        ws.send(message);
        $('#message').val('');
    });

    $('#message').keypress(function(e) {
        if (e.which == 13) { // Enter key pressed
            $('#send').click();
        }
    });
});

This code:

Establishes a WebSocket connection to the PHP server.
Listens for incoming messages and appends them to the #chat-box.
Sends a message when the Send button is clicked or the Enter key is pressed.

Final Thoughts

With this chat application setup, you can add multiple users, making it a fully functional chat room. You can further extend this project by:

Adding user authentication.
Showing active users in a sidebar.
Implementing private chat rooms or channels.
