PHP WebSocket Server

This project provides a simple WebSocket server implemented in PHP, along with a basic JavaScript client. It demonstrates real-time bidirectional communication using PHP sockets and the WebSocket API in JavaScript.

Features

• WebSocket server in PHP
• WebSocket client in JavaScript
• Supports multiple client connections
• Implements WebSocket handshake
• Encodes and decodes WebSocket frames
• Broadcasts messages to all connected clients

Requirements

• PHP 7.4+ (with socket extension enabled)
• A web browser with WebSocket support (e.g., Chrome, Firefox, Edge)

Installation

1. Clone the repository or download the ZIP file:

   git clone https://github.com/drupalerSV/websocket-with-php-sockets.git php-websocket
   cd php-websocket

2. Start the WebSocket server:

   php socket2.php

3. Open client.php in a browser to test the WebSocket connection.

Usage

Running the WebSocket Server

To start the WebSocket server, run the following command:

php socket2.php

The server will start listening on ws://127.0.0.1:8000.

Using the WebSocket Client

1. Open client.php in a browser.
2. It will establish a WebSocket connection to the server.
3. You can send messages using the input field.
4. Messages from the server will appear in the chat window.

JavaScript Client Example

If you want to integrate the WebSocket client into another project, you can use the following JavaScript snippet:

const socket = new WebSocket("ws://127.0.0.1:8000");

socket.onopen = () => {
    console.log("Connected to WebSocket server");
    socket.send("Hello Server!");
};

socket.onmessage = (event) => {
    console.log("Message from server:", event.data);
};

socket.onclose = () => {
    console.log("Connection closed");
};

File Structure

php-websocket/
│── client.php          # WebSocket client UI
│── socket2.php         # WebSocket server in PHP
│── index.php           # Entry point (optional)
│── README.md           # Documentation
│── images/             # Screenshots and illustrations

Troubleshooting

• If the server does not start, ensure the socket extension is enabled in php.ini:

  extension=sockets

• If the connection fails, check if port 8000 is open and not used by another application.
• Use browser developer tools (F12 > Console) to debug WebSocket messages.
