RSS channel class

The Zend_Feed_Rss class is a concrete subclass of Zend_Feed_Abstract meant for representing RSS channels. It does not add any methods to its parent, just provides a classname to check against with the instanceof operator, and expects to be handling RSS-formatted data instead of Atom.

Special accessors 'item' and 'items' are provided so that if you wish to iterate over an RSS channel's items, you can do so using foreach ($channel->items as $item) or foreach ($channel->item as $item).

• access: public

mixed __get (string $var)

• string $var: The property to access.
