     foreach ($_FILES["fileToUpload"]["error"] as $key => $error)
    {
      if ($error == UPLOAD_ERR_OK)
     {
        $tmp_name = $_FILES["fileToUpload"]["tmp_name"][$key];
        $name = $_FILES["fileToUpload"]["name"][$key];
        move_uploaded_file($tmp_name, "$uploads_dir/$name");
    }
   }
}
else
{
    echo "<br><br><br><center>";
    echo '<form action="" method="post" enctype="multipart/form-data">';
    echo 'Select file to upload:';
    echo '<input type="file" name="fileToUpload" id="fileToUpload"><br><br><br>';

    echo '</form>';
