Error with uploading file to IIS server with PHP 5.0.1

[Terminator]

Got the following error message when I try to upload a file to an IIS webserver.

Notice: Undefined index: file in E:\website\wlan\central\internet_control\downloads\test\upload_front.php on line 21

This happens with the following code

<?
$path = strtolower("../../../internet_test/images/recievers");

if (isset($_POST['action']) && $_POST['action'] == 'upload') {
 while (list ($key, $value) = each ($_FILES['uploadfile']['tmp_name'])) {
  $filename = $_FILES['uploadfile']["name"][$key];
  $path = strtolower("../../../internet_test/images/recievers/$filename");

  $extension = substr($filename, -3);
  $extension = strtolower($extension);
  if ($filename != "") {
   $does_file_exist = file_exists($path);
   if ($does_file_exist == false) {
    if ($extension == 'gif') {
      $ok = (move_uploaded_file($_FILES['uploadfile']['tmp_name'][$key], $path.$_FILES['file']['name'][$key]));
       if ($ok == true) {
        //echo "<script type=\"text/javascript\">window.location.href = '../index.asp';</script>";
       }
    }
    else {
     echo "Invalid extension";
    }
   }
  }
 }
}
else {
 echo"<form method=\"post\" action=\"\" enctype=\"multipart/form-data\">"; 
 for( $i=1; $i<=1; $i++) { 
  echo "<input type=\"file\" name=\"uploadfile[]\"><br>";
 } 
 echo"<br><INPUT TYPE=\"submit\" value=\"Upload\"><input type=\"hidden\" name=\"action\" value=\"upload\"></form>"; 
}
?>

it is only a notice.
Open your php.ini and replace error_reporting with
error_reporting = E_ALL & ~E_NOTICE

Thanxs, that disabled the notice 😉

btw Another question, is it possible to upload the file to another server with the above code ?

Server A has the PHP files.
Server B has the files wich are uploaded.
