note 28501 added to language.variables

References are great if you want to point to a variable which you don't quite know the value yet ;) eg: $error_msg = &$messages['login_error']; // Create a reference $messages['login_error'] = 'test'; // Then later on set the referenced value echo $error_msg; // echo the 'referenced value' The output will be: test -- http://www.php.net/manual/en/language.variables.php http://master.php.net/manage/user-notes.php?action=edit+28501 http://master.php.net/manage/user-notes.php?action=delete+28501 http://master.php.net/manage/user-notes.php?action=reject+28501
