consider the following statement:

$_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?
You can use empty() to take one of them out, since "0" is presumably
also not a desired input:
$language = empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])
? "*"
: $_SERVER['HTTP_ACCEPT_LANGUAGE'];
There's a new ?: operator in PHP 6 which will make that even shorter,
however unlike empty(), it currently throws a notice with unset operands.
