if the string is not set, you will get an "undefined index" error when
calling isused(). that's just the problem. you can't reference an
unset string without doing isset first, so putting isset inside the
function is simply too late.

Hi OLav,
what about this ?
$language = isused($_SERVER["HTTP_ACCEPT_LANGUAGE"]);
echo "language is " . $language;
function isused($variable)
{ return isset($variable) && $variable != "" ? $variable : "*";
}
HTH, Cor
