note 82741 added to functions.returning-values

About returning the value from a recursive function If you are calling a recursive function then it would not return the value to the calling function unless you would declare the returning variable as global. for example <?php function GetDestinationChild($id) { global $ar; //do some operation //if some results comes if($cnt>0) { //call itself $this->GetDestinationChild($obj_2->dest_id); } else { //return computed value return $ar; } } ?> if you would not define the returning variable as global it would not return the desired computed value ---- Server IP: 202.89.58.1 Probable Submitter: 202.175.137.165 ---- Manual Page -- http://www.php.net/manual/en/functions.returning-values.php Edit -- https://master.php.net/note/edit/82741 Del: integrated -- https://master.php.net/note/delete/82741/integrated Del: useless -- https://master.php.net/note/delete/82741/useless Del: bad code -- https://master.php.net/note/delete/82741/bad+code Del: spam -- https://master.php.net/note/delete/82741/spam Del: non-english -- https://master.php.net/note/delete/82741/non-english Del: in docs -- https://master.php.net/note/delete/82741/in+docs Del: other reasons-- https://master.php.net/note/delete/82741 Reject -- https://master.php.net/note/reject/82741 Search -- https://master.php.net/manage/user-notes.php
