note 69603 added to function.session-destroy

$_SESSION is the only superglobal whose uninitialized value is not that of an empty array but that of NULL. If there is no reason behind it, I don't know, but I assume there is. Therefore, destroy a $_SESSION by assigning to it NULL. The rationale behind assinging to it array() is that your codes may have loops in it that scan a destroyed session. The fact is, your codes should not have such loops in the first place. A code that loops a destroyed session, is a terribly bad code and no solutions that encourage terribly bad coding prcatices should be sponsored. $_SESSION=null is the _compliant_ way to go. It will pass all tests, included isset($_SESSION). ---- Server IP: 80.241.173.254 Probable Submitter: 84.221.110.198 ---- Manual Page -- http://www.php.net/manual/en/function.session-destroy.php Edit -- https://master.php.net/note/edit/69603 Del: integrated -- https://master.php.net/note/delete/69603/integrated Del: useless -- https://master.php.net/note/delete/69603/useless Del: bad code -- https://master.php.net/note/delete/69603/bad+code Del: spam -- https://master.php.net/note/delete/69603/spam Del: non-english -- https://master.php.net/note/delete/69603/non-english Del: in docs -- https://master.php.net/note/delete/69603/in+docs Del: other reasons-- https://master.php.net/note/delete/69603 Reject -- https://master.php.net/note/reject/69603 Search -- https://master.php.net/manage/user-notes.php
