PHP Sockets loading information into browser

Question

Hello guys I am trying to load some information into the browser. I have this code:

<?php
    // allow the daemon to run without being timed out
    set_time_limit(0);

    $ip = "192.168.0.101";
    $port = 123;

    // set the protocols
    if( !$socket = socket_create(AF_INET,SOCK_STREAM,0) ){
        showError();    
    }

    echo "The socket's protocol info was set \n";

    // bind the socket
    if( !socket_bind($socket,$ip,$port) ){
        showError();
    }
    echo "The socket has been bound to a specific port now ! \n";

    // start listening on this port
    if( !socket_listen($socket) ){
        showError();
    }
    echo "Now listening for connections @ @ @ \n";

    $client = socket_accept($socket);
    echo "new connection with client established !! \n";            
            do {
            // welcome the user
                if(!$clientMsg = socket_read($client, 2048, PHP_NORMAL_READ)) {
                        echo "Error occured while receiving message!\n";
                }

                        if(!$clientMsg = trim($clientMsg)) {
                        continue;
                    }

                    $msg = "Thank you for your message!\n";
                    socket_write($client, $msg, strlen($msg));                    

                    echo "====================================================\n";
                    echo "Message was received successfully!\n";
                    echo $clientMsg."\n";
                    echo "====================================================\n";

                    if ($clientMsg == 'close') {
                        //socket_close($client);
                        break 2;
                    }
        } while (true);
        /*
        // check for any message sent by the user
        do{
            if( ! $clientMssg = socket_read($client,2048,PHP_NORMAL_READ) ){
                showError();
            }

            // say something back
            $messageForUser = "Thanks for your input. Will think about it.";
            socket_write($client,$messageForUser,strlen($messageForUser));

            // was it actually words?
            if( !$clientMssg = trim($clientMssg) ){
                continue;
            }
            if( $clientMssg == 'close' ){
                // close their connection as requested
                socket_close($client);
                echo "\n\n-------------------------------- \n" .
                    "The user has left the connection\n";
                // break out of the loop
                break 2;    
            }

        }while(true); */  
    // end the socket
    echo "Ending the socket \n";
    socket_close($socket);

    // show error details
    function showError( $theSocket = null ){
        $errorcode = socket_last_error($theSocket);
     $errormsg = socket_strerror($errorcode);

     die("Couldn't create socket: [$errorcode] $errormsg");
    }

?>

On the server side, but I dont know how I can made it visible in the browser. Can you help me? I am trying to make a simple chat system just for the sake of understandint the basics and I hope to translate into some more complex data manupulation for games, and live statistics and so on...

Regards!

You can use JavaScript and WebSockets to send requests to your PHP server program and receive the responses. This is a good tutorial using PHP and WebSockets for a chat.
