Simple Live Chat With PHP Websockets (Free Download)

Welcome to a tutorial on how to create a simple live chat application with PHP and WebSockets. Looking to add live chat features to your website or portal? Let us walk through an example in this guide – Read on!

TABLE OF CONTENTS

PHP LIVE CHAT

All right, let us now get into more details on the PHP live chat.

DOWNLOAD RATCHET WEBSOCKET LIBRARY

• As above, a copy of Ratchet is required.
• An easy way is to use Composer to fetch the latest version.
• Open the command line, navigate to your HTTP folder – cd YOUR-HTTP-FOLDER .
• Run composer require cboden/ratchet . This will automatically download the latest version into the vendor/ folder.

PART 1) PHP WEBSOCKET LIVE CHAT

 if (defined("STDIN")) < return true; >if (array_key_exists("SHELL", $_ENV)) < return true; >if (!array_key_exists("REQUEST_METHOD", $_SERVER)) < return true; >if (empty($_SERVER["REMOTE_ADDR"]) && !isset($_SERVER["HTTP_USER_AGENT"]) && count($_SERVER["argv"])>0) < return true; >return false; > if (!is_cli()) < exit("Please run this in the command line."); >// (B) LOAD RATCHET // https://github.com/ratchetphp/Ratchet // composer require cboden/ratchet require "vendor/autoload.php"; use Ratchet\MessageComponentInterface; use Ratchet\ConnectionInterface; use Ratchet\Server\IoServer; use Ratchet\Http\HttpServer; use Ratchet\WebSocket\WsServer; // (C) CHAT CLASS class Chat implements MessageComponentInterface < // (C1) PROPERTIES private $debug = true; // debug mode protected $clients; // connected clients // (C2) CONSTRUCTOR - INIT CLIENTS LIST public function __construct () < $this->clients = new \SplObjectStorage; if ($this->debug) < echo "Chat server started.\r\n"; >> // (C3) ON CLIENT CONNECT - STORE INTO $THIS->CLIENTS public function onOpen (ConnectionInterface $conn) < $this->clients->attach($conn); if ($this->debug) < echo "Client connected: resourceId>\r\n"; > > // (C4) ON CLIENT DISCONNECT - REMOVE FROM $THIS->CLIENTS public function onClose (ConnectionInterface $conn) < $this->clients->detach($conn); if ($this->debug) < echo "Client disconnected: resourceId>\r\n"; > > // (C5) ON ERROR public function onError (ConnectionInterface $conn, \Exception $e) < $conn->close(); if ($this->debug) < echo "Client error: resourceId> | getMessage()>\r\n"; > > // (C6) ON RECEIVING MESSAGE - SEND TO EVERYONE public function onMessage (ConnectionInterface $from, $msg) < $msg = strip_tags($msg); if ($this->debug) < echo "Received message from resourceId>: \r\n"; > foreach ($this->clients as $client) < $client->send($msg); > > > // (D) START! $server = IoServer::factory(new HttpServer(new WsServer(new Chat())), 8080); // @CHANGE if not port 8080 $server->run();

1. A “safety check” to make sure the script is run from the command line.
2. Load and use the Ratchet library.
3. The mechanics of the chat application:
   • (C3) We store all clients into $this->clients when they connect to the WebSocket server.
   • (C4) Remove the clients from $this->clients when they disconnect.
   • (C6) On receiving a message from any client, we loop through $this->clients and forward the message to everyone.
4. Start the live chat server.

Yep. That’s all for the “complicated chat server”.

PART 2) LIVE CHAT PAGE

2A) THE HTML

1. is where we show all the chat messages.
2. is where we ask the user for a name before launching the chat.
3. is the “send message” box. This is hidden at first, will only show after the user enters a name and successfully connects to the WebSocket server.

2B) LIVE CHAT JAVASCRIPT

var chat = < // (A) INIT - GET HTML ELEMENTS host : "ws://localhost:8080/", // @CHANGE to your own! name : "", // current user name socket : null, // websocket object hMsg : null, // html chat messages hName : null, // html set name form hNameSet : null, // html set name field hNameGo : null, // html set name submit hSend : null, // html send message form hSendTxt : null, // html send message field hSendGo : null, // html send message submit init : () =>< chat.hMsg = document.getElementById("chat-messages"); chat.hName = document.getElementById("chat-name"); chat.hNameSet = document.getElementById("chat-name-set"); chat.hNameGo = document.getElementById("chat-name-go"); chat.hSend = document.getElementById("chat-send"); chat.hSendTxt = document.getElementById("chat-send-text"); chat.hSendGo = document.getElementById("chat-send-go"); chat.hNameGo.disabled = false; >, // (B) SWAP BETWEEN SET NAME/SEND MESSAGE FORM swap : direction => < if (direction) < chat.hName.classList.add("hide"); chat.hSend.classList.remove("hide"); >else < chat.hSend.classList.add("hide"); chat.hName.classList.remove("hide"); >>, // (C) START CHAT start : () => < // (C1) SET NAME + SWAP HTML FORM chat.name = chat.hNameSet.value; chat.swap(1); chat.hSendGo.disabled = true; // (C2) CREATE WEB SOCKET chat.socket = new WebSocket(chat.host); // (C3) ON OPEN - ENABLE CHAT chat.socket.onopen = e =>chat.hSendGo.disabled = false; // (C4) ON CLOSE - SWAP BACK TO "SET NAME" chat.socket.onclose = e => chat.swap(0); // (C5) ON RECEIVING DATA - UPDATE HTML CHAT chat.socket.onmessage = e => < let msg = JSON.parse(e.data), row = document.createElement("div"); row.className = "chat-row"; row.innerHTML = `; // (C6) ON ERROR chat.socket.onerror = e => < chat.swap(0); console.error(e); alert(`Failed to connect to $`); >; return false; >, // (D) SEND MESSAGE send : () => < chat.socket.send(JSON.stringify(< n: chat.name, m: chat.hSendTxt.value >)); chat.hSendTxt.value = ""; return false; > >; window.onload = chat.init;

1. init() Runs on window load. All it does is literally get all the HTML elements.
2. swap() Swap the HTML interface between “set name” and “send message”.
3. start() When the user enters the name and clicks on “start”. Long story short, create a WebSocket object, connect to the server, and update the HTML chat on receiving messages.
4. send() Self-explanatory. Send a chat message to the server.

DOWNLOAD & NOTES

Here is the download link to the example code, so you don’t have to copy-paste everything.

SUPPORT

600+ free tutorials & projects on Code Boxx and still growing. I insist on not turning Code Boxx into a «paid scripts and courses» business, so every little bit of support helps.

EXAMPLE CODE DOWNLOAD

Click here for the source code on GitHub gist, just click on “download zip” or do a git clone. I have released it under the MIT license, so feel free to build on top of it or use it in your own project.

EXTRA BITS & LINKS

That’s all for this guide, and here is a small section on some extras that may be useful to you.

IMPROVEMENT IDEAS

• Do a “unique name check” after connecting to the server to make sure that there are no clashes.
• Announce when users connect/disconnect from the chat.
• Save the messages to the database, or store them in the browser.
• If you want to create “chat rooms”, a possibility is to:
  • Turn $clients into a nested array in 1-chat-server.php . For example, $clients[«PUBLIC»] = [] , $clients[«TECH»] = [] , $clients[«LIFE»] = [] .
  • On connect, the client needs to provide the group name, or we will put them into PUBLIC by default.
  • When the client sends a message, forward it to everyone in the group only.

  Yep, the possibilities are endless – It is up to you to complete your own system now.

  DYNAMIC PROPERTIES

  • At the time of writing, PHP 8.2+ throw a lot of “creation of dynamic property is deprecated” for the PHP Ratchet library. If you do not know what that means, follow up with this.
  • The script has set error_reporting(E_ALL & ~E_DEPRECATED) to mute the deprecation notices.
  • Not sure if PHP Ratchet will be updated, will keep a look out and change to another sockets library if required.
  • Other possible “fixes”:
    • Edit the Ratchet library files, add #[\AllowDynamicProperties] before the class definitions.
    • Or set class XYZ extends stdClass

    COMPATIBILITY CHECKS

    Works across all modern browsers.
