    This code could be very helpfull...

    The following code is for the "server". It listen for a message until CTRL-C

    <?php
    while (true)
    {
    // disconnected every 5 seconds...
    receive_message('127.0.0.1','85',5);
    }

    function     receive_message($ipServer,$portNumber,$nbSecondsIdle)
    {
    // creating the socket...
    $socket = stream_socket_server('tcp://'.$ipServer.':'.$portNumber, $errno, $errstr);
    if (!    $socket)
    {
    echo     "$errstr ($errno)<br />\n";
    }
    else
    {
    // while there is connection, i'll receive it... if I didn't receive a message within $nbSecondsIdle seconds, the following function will stop.
    while ($conn = @stream_socket_accept($socket,$nbSecondsIdle))
    {
    $message= fread($conn, 1024);
    echo     'I have received that : '.$message;
    fputs ($conn, "OK\n");
    fclose ($conn);
    }
    fclose($socket);
    }
    }
    ?>

    The following code is for the "client". It send a message, and read the respons...

    <?php

    send_message    ('127.0.0.1','85','Message to send...');

    function     send_message($ipServer,$portServer,$message)
    {
    $fp = stream_socket_client("tcp://$ipServer:$portServer", $errno, $errstr);
    if (!    $fp)
    {
    echo     "ERREUR : $errno - $errstr<br />\n";
    }
    else
    {
    fwrite($fp,"$message\n");
    $response = fread($fp, 4);
    if (    $response != "OK\n")
    {echo     'The command couldn\'t be executed...\ncause :'.$response;}
    else
    {echo     'Execution successfull...';}
    fclose($fp);
    }
    }
    ?>

    To check if there's a new connection waiting, without blocking, or (when using non-blocking mode) without notices), you can use stream_accept (as opposed to socket_select).

    <?php

    class GenericClass {

    protected     $resSocket=null;

    function     acceptConnections() {

    # check that we still have a resource

    if(is_resource($this->resSocket)) {

    $arrRead=array($this->resSocket);

    $arrWrite=array();

    /** @warning Passing $arrRead,$arrWrite by reference */
    if(stream_select($arrRead,$arrWrite,$arrWrite,0)) {

    $resConnection=stream_socket_accept($this->resSocket,0);

    # ... other stuff here
    }
    }
    }
    }
    ?>
