'WebSocket connection to 'ws://..' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

Pulling my hair searching from last 4 hours this simple code for socket connection and getting error. I have changed port as well but nothing works.

 //create a new WebSocket object.
        var wsUri = "ws://localhost:9000/demo/server.php";  
        websocket = new WebSocket(wsUri);

    websocket.onopen = function(ev) { // connection is open 
        $('#message_box').append("<div class=\"system_msg\">Connected!</div>"); //notify user
    }

    $('#send-btn').click(function(){ //use clicks message send button   
        var mymessage = $('#message').val(); //get message text
        var myname = $('#name').val(); //get user name

        if(myname == ""){ //empty name?
            alert("Enter your Name please!");
            return;
        }
        if(mymessage == ""){ //emtpy message?
            alert("Enter Some message Please!");
            return;
        }

        //prepare json data
        var msg = {
        message: mymessage,
        name: myname,
        color : '<?php echo $colours[$user_colour]; ?>'
        };
        //convert and send data to server
        websocket.send(JSON.stringify(msg));
    });

Error :

WebSocket connection to 'ws://localhost:9000/demo/server.php' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED

while the PHP is

$host = 'localhost'; //host
$port = '9000'; //port
$null = NULL; //null var

//Create TCP/IP sream socket
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
//reuseable port
socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);

//bind socket to specified host
socket_bind($socket, 0, $port);

//listen to port
socket_listen($socket);

//create & add listning socket to the list
$clients = array($socket);

You're not creating a websocket server. This is what you need: http://socketo.me/

Getting websockets to work properly in PHP is annoying and a mess (especially, if you're a beginner). You might be over your head.

Solution 2:[2]

Your PHP uses a regular (raw) tcp/ip socket connection. Websockets is a protocol with a specific handshake and packet framing... if the server doesn't speak "Websockets", the client will raise an error.

P.S.

PHP was originally designed to act as a web app scripting language for HTTP connections, usually using CGI to quickly return a String that acts as the file/html to be sent.

By nature, PHP processes are intended to have shorter life-spans.

I would not recommend using PHP to write a websocket server, although you could look into Ratchet which is a PHP websocket library that could help you to build a websocket app using PHP.

I recommend you consider Ruby, node.js or Python for your Websocket project - it will save you a lot of headaches as you dig deeper into your project and you are likely to have better community support for any challenges you face along the way.

Try to switch off all antivirus the maybe blocking sockets port for protection.
