I am trying to create a chat application using Socket and using Swoole as backend. I successfully create a connection to server-client but the issue I am facing now is that whenever I close terminal WebSocket is unable to connect. Server code:-
<?php
//Create the websocket server object
$websocket_server = new swoole_websocket_server("MY_IP", 3000);
// Register function of the opening connection event
$websocket_server->on('open', function($websocket_server, $request){
var_dump($request->fd, $request->get, $request->server);
$websocket_server->push($request->fd, "Hello welcome
");
});
// Register function of the receiving message event
$websocket_server->on('message', function($websocket_server, $frame){
echo "Message : {$frame->data}
";
$websocket_server->push($frame->fd, "Server : {$frame->data}");
});
// Register function of the close event
$websocket_server->on('close', function($websocket_server, $fd){
echo "client_{$fd} is closed
";
});
// Start the server
$websocket_server->start();
Client side Code:-

<script type="text/javascript">
var wsServer = 'ws://IP:3000';
var websocket = new WebSocket(wsServer);
websocket.onopen = function (evt) {
console.log("Connected to WebSocket server.");
};
websocket.onclose = function (evt) {
console.log("Disconnected");
};
websocket.onmessage = function (evt) {
console.log('Retrieved data from server: ' + evt.data);
};
websocket.onerror = function (evt, e) {
console.log('Error occured: ' + evt.data);
};
</script>
</body>
</html>
Everything is working fine the only issue is when we close terminal web socket id down.
