note 101930 added to function.unset

edouard dot berge: See the doc. page for isset, which states "Returns TRUE if var exists and has value other than NULL, FALSE otherwise.". Your array $tab is empty, but does have a non-NULL value, so isset($tab) properly returns true. ---- Server IP: 69.147.83.197 Probable Submitter: 165.212.186.27 ---- Manual Page -- http://www.php.net/manual/en/function.unset.php Edit -- https://master.php.net/note/edit/101930 Del: integrated -- https://master.php.net/note/delete/101930/integrated Del: useless -- https://master.php.net/note/delete/101930/useless Del: bad code -- https://master.php.net/note/delete/101930/bad+code Del: spam -- https://master.php.net/note/delete/101930/spam Del: non-english -- https://master.php.net/note/delete/101930/non-english Del: in docs -- https://master.php.net/note/delete/101930/in+docs Del: other reasons-- https://master.php.net/note/delete/101930 Reject -- https://master.php.net/note/reject/101930 Search -- https://master.php.net/manage/user-notes.php
