Access SimpleXML node value as string

Question

I have an object called $picasa_feed like this:

SimpleXMLElement Object
(
    [guid] => https://picasaweb.google.com/data/entry/base/user/0000000000000000/albumid/0000000000000000?alt=rss&hl=en_US
    [pubDate] => Fri, 12 Dec 2008 20:00:00 +0000
    [category] => http://schemas.google.com/photos/2007#album
    [title] => My Pictures
    [description] => ...
    [link] => https://picasaweb.google.com/0000000000000000/MyAlbum
    [author] => Me
)

I want to take put a property value into an element of an associative array:

$data_to_save['title'] = $picasa_feed->title;

When I do that the value of $data_to_save is

Array
(
    [title] => SimpleXMLElement Object
        (
            [0] => My Pictures
        )
}

What I want is

Array
(
    [title] => My Pictures
}

What am I doing wrong and how do I fix it?

Answer 1

将其转换为字符串：

$data_to_save['title'] = (string) $picasa_feed->title;

Answer 2

You want to invoke the SimpleXMLElement's magic __toString method by casting it to string. Try: $data_to_save['title'] = (string)$picasa_feed->title;

Answer 3

这应该工作：

$data_to_save['title'] = (string) $picasa_feed->title;
