note 119157 added to function.define

In case someone else is curious like me, defining a variable to "false", actually undefining it: define ("A", false); if (defined("A")) echo A; will echo nothing. Useful, when you need to define, for example, log and keep definition without actually having it defined. ---- Server IP: 72.52.91.14 Probable Submitter: 78.83.76.220 ---- Manual Page -- http://php.net/manual/en/function.define.php Edit -- https://master.php.net/note/edit/119157 Del: integrated -- https://master.php.net/note/delete/119157/integrated Del: useless -- https://master.php.net/note/delete/119157/useless Del: bad code -- https://master.php.net/note/delete/119157/bad+code Del: spam -- https://master.php.net/note/delete/119157/spam Del: non-english -- https://master.php.net/note/delete/119157/non-english Del: in docs -- https://master.php.net/note/delete/119157/in+docs Del: other reasons-- https://master.php.net/note/delete/119157 Reject -- https://master.php.net/note/reject/119157 Search -- https://master.php.net/manage/user-notes.php
