Answer 1

Each $item is of type SimpleXMLElement.

Now you can loop the children using the namespace http://search.yahoo.com/mrss/ and then you can access the attributes.

For example:

foreach($xml->channel->item as $item) {
    foreach($item->children("http://search.yahoo.com/mrss/") as $media) {
        $img = (string)$media->attributes()->url;
    }
}
