مشکل در اتصال به سرور با websoket

من دارم وب سوکت با php رو یاد میگیرم . الان دو تا فایل روی سرور اجرا می کنم که با هم کانکت می شن و دیتا هم می فرستن و میگیرن ولی وقتی با جاوا اسکریپت می خوام کانکت شم ارور میده.

myServer.php

$host = "localhost";

$port = 800;

set_time_limit(0);

$socket = socket_create(AF_INET, SOCK_STREAM, 0);

$result = socket_bind($socket, $host, $port);

$result = socket_listen($socket, 3);

$spawn = socket_accept($socket);

$input = socket_read($spawn, 1024);

$input = trim($input);

echo "Client Message : ".$input;

$output = strrev($input) . "\n";

socket_write($spawn, $output, strlen ($output));

socket_close($spawn);

socket_close($socket);

server.php

$host    = "localhost";

$port    = 800;

$message = "Hello APPACK";

echo "Message To server :".$message.'<br>';

$socket = socket_create(AF_INET, SOCK_STREAM, 0);

$result = socket_connect($socket, $host, $port); 

socket_write($socket, $message, strlen($message));

$result = socket_read ($socket, 1024);

echo "Reply From Server :".$result;

socket_close($socket);

اینم کد جاوا اسکریپت

$(document).ready(function(){

    var host = 'localhost';

    var port = '800';

    var msgBox = $('#message-box');

    var wsUri = "ws://" + host + ":" + port + "/socket/myServer.php"; 

    console.log(wsUri);

    websocket = new WebSocket(wsUri,'echo-protocol'); 

    websocket.onopen = function(ev) {

        msgBox.append('<div class="system_msg" style="color:#bbbbbb">Welcome to my "Chat box"!</div>');    

    }

    websocket.onmessage = function(ev) {

        var response = JSON.parse(ev.data); 

        var res_type = response.type;

        var user_message = response.message;

        var user_name = response.name;

        var user_color = response.color;

        switch(res_type){

            case 'usermsg':

                msgBox.append('<div><span class="user_name" style="color:' + user_color + '">' + user_name + '</span> : <span class="user_message">' + user_message + '</span></div>');

                break;

            case 'system':

                msgBox.append('<div style="color:#bbbbbb">' + user_message + '</div>');

                break;

        }

        msgBox[0].scrollTop = msgBox[0].scrollHeight;

    };



    websocket.onerror = function(ev){

        msgBox.append('<div class="system_error">Error Occurred - ' + ev.message + '</div>');

    }; 

    websocket.onclose = function(ev){

        msgBox.append('<div class="system_msg">Connection Closed</div>');

    }; 

    $('#send-message').click(function(){

        send_message();

    });

    $("#message").on("keydown",function(event){

         if(event.which==13){

             send_message();

         }

    });



    function send_message(){

        var message_input = $('#message');

        var name_input = $('#name'); 

        if(message_input.val() == ""){

            alert("Enter your Name please!");

            return;

        }

        if(message_input.val() == ""){

            alert("Enter Some message Please!");

            return;

        }

        var msg = {

            message: message_input.val(),

            name: name_input.val(),

            color : '<?php echo $colors[$color_pick]; ?>'

        };

        websocket.send(JSON.stringify(msg));

        message_input.val('');

    }

});

Firefox can’t establish a connection to the server at ws://localhost:800/socket/myServer.php. actions.js
کروم هم این رو
