note 92296 added to function.define

A note on redefining: Constants can't be redefined: $ php -r "define('A', 1); var_dump('A'); define('A', 2); var_dump('A');"; string(1) "A" PHP Notice: Constant A already defined in Command line code on line 1 string(1) "A" But using the case insensitive setting shows that the internal representation is lower case: $ php -r "define('A', 1, true); var_dump('A'); define('A', 2); var_dump('A');"; string(1) "A" string(1) "A" Note the lower case 'a' in the second define() here: $ php -r "define('A', 1, true); var_dump('A'); define('a', 2); var_dump('A');"; string(1) "A" PHP Notice: Constant a already defined in Command line code on line 1 string(1) "A" ---- Server IP: 64.71.164.2 Probable Submitter: 148.87.1.167 ---- Manual Page -- http://www.php.net/manual/en/function.define.php Edit -- https://master.php.net/note/edit/92296 Del: integrated -- https://master.php.net/note/delete/92296/integrated Del: useless -- https://master.php.net/note/delete/92296/useless Del: bad code -- https://master.php.net/note/delete/92296/bad+code Del: spam -- https://master.php.net/note/delete/92296/spam Del: non-english -- https://master.php.net/note/delete/92296/non-english Del: in docs -- https://master.php.net/note/delete/92296/in+docs Del: other reasons-- https://master.php.net/note/delete/92296 Reject -- https://master.php.net/note/reject/92296 Search -- https://master.php.net/manage/user-notes.php
