note 79893 added to function.array-walk

Jon Langevin code : <?php array_walk($array1, 'userfunction', &$array2byreference); function userfunction(&$array1value, $key, $array2){ // process $array1value and $array2, $array2 will retain the values } ?> gives a php warning (call time by reference etc ...) (PHP 5.2.5 and others I suppose) Is there a clue for this ? ---- Server IP: 217.174.196.197 Probable Submitter: 86.209.191.181 ---- Manual Page -- http://www.php.net/manual/en/function.array-walk.php Edit -- https://master.php.net/note/edit/79893 Del: integrated -- https://master.php.net/note/delete/79893/integrated Del: useless -- https://master.php.net/note/delete/79893/useless Del: bad code -- https://master.php.net/note/delete/79893/bad+code Del: spam -- https://master.php.net/note/delete/79893/spam Del: non-english -- https://master.php.net/note/delete/79893/non-english Del: in docs -- https://master.php.net/note/delete/79893/in+docs Del: other reasons-- https://master.php.net/note/delete/79893 Reject -- https://master.php.net/note/reject/79893 Search -- https://master.php.net/manage/user-notes.php
