note 113999 added to class.splstack

There are bug reports and the like noting that SplStack can't be serialized and unserialized until PHP v5.4. This means that in v5.3 and prior, you can't store an SplStack in $_SESSION. The second access of $_SESSION will have an empty SplStack. ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/class.splstack.php Edit -- https://master.php.net/note/edit/113999 Del: integrated -- https://master.php.net/note/delete/113999/integrated Del: useless -- https://master.php.net/note/delete/113999/useless Del: bad code -- https://master.php.net/note/delete/113999/bad+code Del: spam -- https://master.php.net/note/delete/113999/spam Del: non-english -- https://master.php.net/note/delete/113999/non-english Del: in docs -- https://master.php.net/note/delete/113999/in+docs Del: other reasons-- https://master.php.net/note/delete/113999 Reject -- https://master.php.net/note/reject/113999 Search -- https://master.php.net/manage/user-notes.php
