Create a exercise folder. Open it and run composer require.
composer require gemblue/php-websocket - Make server file executable
sudo chmod +x ./vendor/gemblue/php-websocket/bin/server - Run websocket server with port option
./vendor/gemblue/php-websocket/bin/server port:3000 Then it will show success output like
Listening incoming request on port 3000 .. Create a HTML file for websocket client, for example index.html :
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css"> <div class="container"> <div class="card mt-5 mb-3"> <div class="card-body"> <div id="output"></div> </div> </div> <div class="form-group"> <label>Nama</label> <input id="name" class="form-control"/> </div> <div class="form-group"> <label>Pesan</label> <textarea id="message" class="form-control"></textarea> </div> <button id="btn-send" class="btn btn-success">Send</button> </div> <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script> <script> function showMessage(messageHTML) { $('#output').append(messageHTML); } $(document).ready(function(){ var websocket = new WebSocket("ws://127.0.0.1:3000"); websocket.onopen = function(event) { showMessage("<div class='text-success'>Berhasil masuk room ..</div>"); } websocket.onmessage = function(event) { var Data = JSON.parse(event.data); showMessage("<div>"+Data.message+"</div>"); $('#message').val(''); }; websocket.onerror = function(event){ showMessage("<div>Problem due to some Error</div>"); }; websocket.onclose = function(event){ showMessage("<div>Connection Closed</div>"); }; $('#btn-send').on("click",function(event){ event.preventDefault(); var messageJSON = { name: $('#name').val(), message: $('#message').val() }; websocket.send(JSON.stringify(messageJSON)); }); }); </script>Open index.html with your browser. Use 2 tab/browser for simulation. Output will be like this :
