note 82849 added to functions.arguments

This issue cropped up in a CakePHP app but I think our problem is more related to something we don't understand about PHP. It seems invocation ofvia $this of a method in an associated class does not properly handle arguments by reference. In a Bait controller class (BaitController) a function foo from the Bait model class is invoked - $this is properly instantiated: function test() { Bait::foo($xxx); // works correctly $this->Bait->foo($xxx); // does not work } In Bait model function foo() takes the parm by ref and sets it's value: function foo(&$msg) { $msg = "HOWDY DOODY"; } ERROR is Undefined variable: xxx ... If you put function foo within the Bait controller class $this->foo() works fine. However if you put it in the model Class using the $this->Bait->foo() invocation syntax seems to ignore the parameter by reference although it does call the function. What's up with that? ---- Server IP: 69.147.83.197 Probable Submitter: 71.199.225.31 ---- Manual Page -- http://www.php.net/manual/en/functions.arguments.php Edit -- https://master.php.net/note/edit/82849 Del: integrated -- https://master.php.net/note/delete/82849/integrated Del: useless -- https://master.php.net/note/delete/82849/useless Del: bad code -- https://master.php.net/note/delete/82849/bad+code Del: spam -- https://master.php.net/note/delete/82849/spam Del: non-english -- https://master.php.net/note/delete/82849/non-english Del: in docs -- https://master.php.net/note/delete/82849/in+docs Del: other reasons-- https://master.php.net/note/delete/82849 Reject -- https://master.php.net/note/reject/82849 Search -- https://master.php.net/manage/user-notes.php
