note 86642 added to security.globals

BEWARE of using register_globals = On, it's not only bad karma but highly dangerous. Consider the following coding: <?php // assume $_SESSION['user'] = array('Hello', 'World'); // assume session_start() was called somewhere before. print('<pre>Contents of array $_SESSION[\'user\']'); print_r($_SESSION['user']); print('<hr>Contents of array $user (PHP SETUP register_globals = On)'); print_r($user); print('</pre>'); ?> If you manipulate $user you'll manipulate $_SESSION['user'] as well with PHP SETUP register_globals = On. So please avoid it at any cost, no serious programmer would ever want to have register_globals = On. ---- Server IP: 81.223.48.75 Probable Submitter: 86.32.238.19 ---- Manual Page -- http://www.php.net/manual/en/security.globals.php Edit -- https://master.php.net/note/edit/86642 Del: integrated -- https://master.php.net/note/delete/86642/integrated Del: useless -- https://master.php.net/note/delete/86642/useless Del: bad code -- https://master.php.net/note/delete/86642/bad+code Del: spam -- https://master.php.net/note/delete/86642/spam Del: non-english -- https://master.php.net/note/delete/86642/non-english Del: in docs -- https://master.php.net/note/delete/86642/in+docs Del: other reasons-- https://master.php.net/note/delete/86642 Reject -- https://master.php.net/note/reject/86642 Search -- https://master.php.net/manage/user-notes.php
