note 21849 added to ref.classobj

Okay, I'm confused. In my book (PHP Programming) it says I can reference variables passed to the function like this: <pre>function func($this->variable)</pre> But this doesn't appear to work. If I want to alter and return $variable, is the only way I can do it like this: <pre>function func($variable) { $this-variable = $variable; }</pre> -- http://www.php.net/manual/en/ref.classobj.php http://master.php.net/manage/user-notes.php?action=edit+21849 http://master.php.net/manage/user-notes.php?action=delete+21849 http://master.php.net/manage/user-notes.php?action=reject+21849
