Question

I am using javascript to connect websocket:

<script>
    var socket;  
    var host = "ws://localhost:8000/socket/server/startDaemon.php";  
    var socket = new WebSocket(host);  
</script>

I got the error:

Can’t establish a connection to the server at

var host = "ws://localhost:8000/socket/server/startDaemon.php";
var socket = new WebSocket(host);

How can I solve this issue?

NOTE : I enabled websocket in mozilla to support web socket application.
and when i run in chrome i got error:

   can't establish a connection to the server at ws://localhost:8000/socket/server/startDaemon.php. var socket = new WebSocket(host);

I solved my error by following code through this link

http://www.flynsarmy.com/2010/05/php-web-socket-chat-application/
and created socketWebSocketTrigger.class.php file for response message where code as

class socketWebSocketTrigger
{   

        function responseMessage($param)
        {
            $a = 'Unknown parameter';

            if($param == 'age'){
                $a = "Oh dear, I'm 152";
            }

            if($param == 'hello'){
                $a = 'hello, how are you?';
            }

            if($param == 'name'){
                $a = 'my name is Mr. websocket';
            }

            if($param == 'today'){
                $a = date('Y-m-d');
            }

            if($param == 'hi'){
                $a = 'hi there';
            }

            return $a;

        }

}

and added code in send function of ‘WebSocketServer.php’ for calling ‘responseMessage’ function which response request message

 public function send($client, $msg){
        $this->say("> ".$msg);
        $messageRequest = json_decode($msg,true);

            // $action=$messageRequest[0];
            $action = 'responseMessage';
            $param  = $messageRequest[1]['data'];
        if( method_exists('socketWebSocketTrigger',$action) ){
                                $response = socketWebSocketTrigger::$action($param);
                            }
            $msg = json_encode(
                array(                      
                'message',
                    array('data' => $response)
                )
            );

            $msg = $this->wrap($msg);

        socket_write($client, $msg, strlen($msg));
    }

it’s working great.
