How To Create Live Streaming Website In Php

Creating a live streaming website using PHP is an excellent way to provide real-time content to your users. In this blog post, we will guide you through the steps needed to create a simple live streaming website using PHP and JavaScript.


  • PHP 7 or higher
  • MySQL (for storing chat messages)
  • A web server (Apache or Nginx)
  • WebRTC (for live streaming)

Step 1: Set up the Database

First, we need to set up a MySQL database to store chat messages. Execute the following SQL query to create a table:

CREATE TABLE `chat_messages` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `username` varchar(255) NOT NULL,
    `message` text NOT NULL,
    `timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
    PRIMARY KEY (`id`)

Step 2: Create a PHP Script for the Chat Server

Create a new PHP file called chat.php and add the following code:

header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');

// Replace with your own database credentials
$db = new PDO('mysql:host=localhost;dbname=your_db_name;charset=utf8', 'your_db_username', 'your_db_password');

while (true) {
    $query = $db->query('SELECT * FROM chat_messages ORDER BY timestamp DESC LIMIT 10');
    $messages = $query->fetchAll(PDO::FETCH_ASSOC);
    $messages = array_reverse($messages);

    foreach ($messages as $message) {
        echo "data: " . json_encode($message) . "\n\n";


This script connects to the MySQL database, retrieves the latest chat messages, and sends them to the client using Server-Sent Events (SSE).

Step 3: Create the HTML Structure

Create a new HTML file called index.html and add the following code:

<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Live Streaming Website</title>

    <div id="chat"></div>
    <form id="messageForm">
        <input type="text" id="username" placeholder="Username">
        <input type="text" id="message" placeholder="Message">
        <button type="submit">Send</button>

    <script src="chat.js"></script>


Step 4: Create the JavaScript Code

Create a new JavaScript file called chat.js and add the following code:

const chat = document.getElementById('chat');
const messageForm = document.getElementById('messageForm');
const usernameInput = document.getElementById('username');
const messageInput = document.getElementById('message');

const source = new EventSource('chat.php');
source.onmessage = (event) => {
    const data = JSON.parse(;
    const messageElement = document.createElement('div');
    messageElement.innerHTML = `<strong>${data.username}</strong>: ${data.message}`;

messageForm.addEventListener('submit', (event) => {
    const username = usernameInput.value;
    const message = messageInput.value;

    if (!username || !message) {
        alert('Please enter a username and message.');

    fetch('send_message.php', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded',
        body: `username=${encodeURIComponent(username)}&message=${encodeURIComponent(message)}`,

    messageInput.value = '';

This code listens for new messages from the chat.php script and appends them to the chat div. It also sends new messages to the server using the Fetch API.

Step 5: Create a PHP Script for Sending Messages

Create a new PHP file called send_message.php and add the following code:

    // Replace with your own database credentials
    $db = new PDO('mysql:host=localhost;dbname=your_db_name;charset=utf8', 'your_db_username', 'your_db_password');

    $username = $_POST['username'] ?? '';
    $message = $_POST['message'] ?? '';

    if ($username && $message) {
        $stmt = $db->prepare('INSERT INTO chat_messages (username, message) VALUES (?, ?)');
        $stmt->execute([$username, $message]);

Step 6: Integrate WebRTC for Live Streaming

Now it’s time to integrate WebRTC for live streaming. There are several libraries available to simplify the process, such as SimpleWebRTC. Follow the instructions provided by the library to set up live streaming on your website.


You now have a basic live streaming website with chat functionality using PHP and JavaScript. You can further customize the design and add more features, such as user authentication and moderation tools. Happy streaming!
