Note Submitter: daevid at daevid dot com ---- Be aware that undefined constants are not evaluated the same as undefined variables (which is frustratingly counter-intuitive)... $ php -a php > if (!DO_IT) echo "don't do it\n"; else echo "do it\n"; do it php > var_dump(DO_IT); string(5) "DO_IT" php > if (!$DO_IT) echo "don't do it\n"; else echo "do it\n"; don't do it php > var_dump($DO_IT); NULL You have to specifically check for the definition like so... php > if(!defined('DO_IT') || (defined('DO_IT') && !DO_IT))echo "don't do it\n"; else echo "do it\n"; don't do it *sigh*
