note 24484 added to language.variables

If you use global variables within a function, take note that changing the variable keyword from "global", somewhere down the line, to "return", that that variable can either be one or the other. It can't be both "returned" and "global". So, if within a function you have on line x: global $var; and then on line x+1: return $var; that $var becomes no longer global, and instead just and only "returned". -- http://www.php.net/manual/en/language.variables.php http://master.php.net/manage/user-notes.php?action=edit+24484 http://master.php.net/manage/user-notes.php?action=delete+24484 http://master.php.net/manage/user-notes.php?action=reject+24484
