another idea is just to redirect certain languages to an online translator like babelfish that translates the page you're on
Code:
<?php
$mypage = "www.gfy.com/index.php";
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
if ($lang == "de"){
$url = "http://babelfish.yahoo.com/translate_url?doit=done&tt=url&intl=1&fr=bf-home&trurl=http%3A%2F%2F$mypage&lp=en_$lang&btnTrUrl=Translate";
header("Location: $url");
exit;
}
?>
