note 115592 added to language.namespaces.definition

It's not very useful, but namespaces make possible to implement an old C joke "#define TRUE FALSE" in PHP. <?php define('TRUE', FALSE); var_dump(TRUE); ?> Results to: bool(true) But if we use namespaces: <?php namespace foo; // Happy degugging! define(__NAMESPACE__ . '\TRUE', \FALSE); define(__NAMESPACE__ . '\FALSE', \TRUE); define(__NAMESPACE__ . '\true', \FALSE); define(__NAMESPACE__ . '\false', \TRUE); if (false && FALSE) { echo 'Hello from the dark side.'; } if(true || TRUE) { echo 'Light side is never defeated.'; } ?> This will output: Hello from the dark side. ---- Server IP: 72.52.91.14 Probable Submitter: 194.187.206.252 ---- Manual Page -- http://php.net/manual/en/language.namespaces.definition.php Edit -- https://master.php.net/note/edit/115592 Del: integrated -- https://master.php.net/note/delete/115592/integrated Del: useless -- https://master.php.net/note/delete/115592/useless Del: bad code -- https://master.php.net/note/delete/115592/bad+code Del: spam -- https://master.php.net/note/delete/115592/spam Del: non-english -- https://master.php.net/note/delete/115592/non-english Del: in docs -- https://master.php.net/note/delete/115592/in+docs Del: other reasons-- https://master.php.net/note/delete/115592 Reject -- https://master.php.net/note/reject/115592 Search -- https://master.php.net/manage/user-notes.php
