Can I have your help please ?

Hi,

I'd like make de chat with PHP-GTK.

But, I have some errors.

Here is the code:

==============================================

<?
if(strtoupper(substr(PHP_OS, 0, 3)) == 'WIN')
  dl('php_gtk.dll');
else
  dl('php_gtk.so');

// Début des fonctions
function false()
  {
  return false;
  }

function quitter()
  {
  GTK::main_quit();
  }

function get_msg()
  {
  global $ifp;
  $ipointer = 0;
  $fp = fopen("http://www.dinsoft.net/softdy/chat/get_msg.php","r");
  while($ipointer <= $ifp)
    {
    $ligne = fgets($fp, 65);
    $ipointer++;
    }

  $ifp++;
  fclose($fp);
  return $ligne;
  }

// Fin des fonctions

// Création de la fenêtre principale
 $window = &new GtkWindow();
 $window->set_title('Softdy FTP: Le chat');
 $window->set_name('principal');
 $window->connect('destroy', 'quitter');
 $window->connect('delete-event', 'false');

$vbox = &new GtkVBox();

$msg = &new GtkEntry();
$zone = &new GtkText();
$zone->set_editable(1);

function update()
  {
  global $pause, $old_buffer, $vbox, $window, $zone, $msg;
  while($pause == 0)
    {
    if($change == 1)
      {
      $buffer = get_msg();
      if($buffer != "$old_buffer")
        {
        $zone->insert(NULL, NULL, NULL, $buffer, strlen($buffer));
        $old_buffer = $buffer;
        }
      $change = 0;
      }
    else
      {
      if($i == 0)
        {
        $vbox->pack_start($zone);
        $vbox->pack_start($msg);
        $window->add($vbox);
        $window->show_all();
        $i++;
        }
      $change = 1;
      }
    }
  }
update();
GTK::main();
?>

==============================================
