what about this ?
$language = isused($_SERVER["HTTP_ACCEPT_LANGUAGE"]);
This call will raise a notice if that array element does not exist.
echo "language is " . $language;
function isused($variable)
{ return isset($variable) && $variable != "" ? $variable : "*";
}
The isset is redundant here. It's been passed as an argument so it
definitely exists.

Subject: repetition of tedious references
consider the following statement:
$language =
isset($_SERVER["HTTP_ACCEPT_LANGUAGE"]) &&
$_SERVER["HTTP_ACCEPT_LANGUAGE"] != "" ?
$_SERVER["HTTP_ACCEPT_LANGUAGE"] : "*";
when using strings in arrays that may be non-existing or empty, you
have to repeat the reference *three* times, which gets excessive and
unreadable.
is there any way to only have to write
$_SERVER["HTTP_ACCEPT_LANGUAGE"] only once?
i know it's possible to supress "is not set" with @, but that just
seems wrong in case there really is an error in the statement.
i love php, but this is one of my pet peeves.
