note 55765 added to ref.session

the following: <?php $_SESSION = array_merge($_SESSION, $myvars) ; ?> unregisters any variable in $_SESSION array, while the following : <?php foreach($myvars as $key => $value) $_SESSION[$key] = $value ; ?> does not. I don't see the point. What should be avoided using this weird $_SESSION array ? ---- Manual Page -- http://www.php.net/manual/en/ref.session.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55765 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55765&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55765&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55765&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55765&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55765&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55765&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55765&report=yes Search -- http://master.php.net/manage/user-notes.php
