[php] php_network_getaddresses: getaddrinfo failed: No such host is known

["HELP!" <izoduwa@xxxxxxxxx>]

Hi,
 error:
php_network_getaddresses: getaddrinfo failed: No such host is known

 $fstream = stream_socket_client("$con:$ip:$port", $errno, $errstr,
$timeout);

 if($fstream){
  $br = fwrite($fstream,$login_request_block);
  $str = stream_get_contents($fstream);
  print( "Connection successful: $str ");
 }
 else{
  return  " str: $str<br>write:$br<br> $errstr ($errno)";
 }

What could be the error
