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.

Methods

__call(string $var, mixed $unused) : mixed

inherited

Get the value of an element with method syntax.

Inherited from: \Zend_Feed_Element::__call()\Zend_Feed_Abstract::__call()

Map method calls to get the string value of the requested element. If there are multiple elements that match, this will return an array of those objects.

Parameters

Name	Type	Description
$var	string	The element to get the string value of.
$unused	mixed	This parameter is not used.

Returns

Type	Description
mixed	The node's value, null, or an array of nodes.

__construct(string $uri = null, string $string = null, \Zend_Feed_Builder_Interface $builder = null) : void

inherited

Feed constructor

Inherited from: \Zend_Feed_Abstract::__construct()

The Zend_Feed_Abstract constructor takes the URI of a feed or a feed represented as a string and loads it as XML.

Parameters

Name	Type	Description
$uri	string	The full URI of the feed to load, or NULL if not retrieved via HTTP or as an array.
$string	string	The feed as a string, or NULL if retrieved via HTTP or as an array.

Throws

Exception	Description
\Zend_Feed_Exception	If loading the feed failed.

__get(string $var) : mixed

Make accessing some individual elements of the channel easier.
