note 83991 added to function.settype

Yes, just look for the ampersand (&) in the function signature. Here you see: bool settype ( mixed &$var , string $type ) There is an & before the first parameter ($var). This means the variable is passed in by reference. So the function is working with the original variable and not a copied local version. You will see this in other php functions such as asort(); References Explained: http://us3.php.net/manual/en/language.references.php ---- Server IP: 209.41.74.194 Probable Submitter: 216.82.221.10 ---- Manual Page -- http://www.php.net/manual/en/function.settype.php Edit -- https://master.php.net/note/edit/83991 Del: integrated -- https://master.php.net/note/delete/83991/integrated Del: useless -- https://master.php.net/note/delete/83991/useless Del: bad code -- https://master.php.net/note/delete/83991/bad+code Del: spam -- https://master.php.net/note/delete/83991/spam Del: non-english -- https://master.php.net/note/delete/83991/non-english Del: in docs -- https://master.php.net/note/delete/83991/in+docs Del: other reasons-- https://master.php.net/note/delete/83991 Reject -- https://master.php.net/note/reject/83991 Search -- https://master.php.net/manage/user-notes.php
