note 89533 added to function.array-merge

This bit me with $_POST when none of the controls were successful. ---- Server IP: 69.147.83.197 Probable Submitter: 76.245.68.102 ---- Manual Page -- http://www.php.net/manual/en/function.array-merge.php Edit -- https://master.php.net/note/edit/89533 Del: integrated -- https://master.php.net/note/delete/89533/integrated Del: useless -- https://master.php.net/note/delete/89533/useless Del: bad code -- https://master.php.net/note/delete/89533/bad+code Del: spam -- https://master.php.net/note/delete/89533/spam Del: non-english -- https://master.php.net/note/delete/89533/non-english Del: in docs -- https://master.php.net/note/delete/89533/in+docs Del: other reasons-- https://master.php.net/note/delete/89533 Reject -- https://master.php.net/note/reject/89533 Search -- https://master.php.net/manage/user-notes.php
