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);
  }
}
