note 98087 added to function.constant

Checking if a constant is empty is bork... You cannot <?php define('A', ''); define('B', 'B'); if (empty(B)) // syntax error if (empty(constant('B'))) // fatal error // so instead, thanks to LawnGnome on IRC, you can cast the constants to boolean (empty string is false) if (((boolean) A) && ((boolean) B)) // do stuff ?> ---- Server IP: 69.147.83.197 Probable Submitter: 62.163.185.42 ---- Manual Page -- http://www.php.net/manual/en/function.constant.php Edit -- https://master.php.net/note/edit/98087 Del: integrated -- https://master.php.net/note/delete/98087/integrated Del: useless -- https://master.php.net/note/delete/98087/useless Del: bad code -- https://master.php.net/note/delete/98087/bad+code Del: spam -- https://master.php.net/note/delete/98087/spam Del: non-english -- https://master.php.net/note/delete/98087/non-english Del: in docs -- https://master.php.net/note/delete/98087/in+docs Del: other reasons-- https://master.php.net/note/delete/98087 Reject -- https://master.php.net/note/reject/98087 Search -- https://master.php.net/manage/user-notes.php
