consider the following statement:

$_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.
Maybe this?
<?php
$v = @$_SERVER['xpy'];
echo ( empty($v) ? '*' : $v );
