Re: repetition of tedious references

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 ----- Original Message ----- From: "Olav Mørkrid" <olav.morkrid@gmail.com> To: "PHP General List" <php-general@lists.php.net> Sent: Wednesday, July 18, 2007 1:24 PM Subject: [PHP] 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. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
