}
$language_name = getLanguageName($_SESSION[\"language\"]);
include \"lang/\".$language_name.\".inc\";
?>
<SELECT NAME=\"language\" id=\"language\" onchange=\"changeLanguage(this)\">
<?php
  $language_array = array_language();
  foreach($language_array as $key => $value){
    if($_SESSION[\"language\"] == $value){
      $selected = \"selected = \'selected\' \";
    }else{
      $selected = \"\";
    }
?>
<OPTION VALUE=\"<?php echo $value;?>\" <?php echo $selected;?>><?php echo getLanguageName($value);?></OPTION>;
<?
  }
?>
</SELECT>
<?php
  if($_GET[\"language\"] == $value){
