@ in tags

Why are we using brackets () after attributes tag?

Example: $xml->channel->item[$random]->enclosure->attributes()->url

var_dump of that part in xml documentgs: object(SimpleXMLElement)#25 (1) { ["@attributes"]=> array(3) { ["url"]=> string(72) "http://traffic.libsyn.com/thegeekyfreelancer/FreeTheGeek-Episode0021.mp3" ["length"]=> string(8) "77471162" ["type"]=> string(11) "audio/x-mp3" } }

basically, this is known as method chaining and you are calling on the method attribute() from within the class that is instantiated with the $xml object.

Hope this helps.
