PHP对象-如何访问此值

Question

I have this link http://lazhalazha.livejournal.com/data/rss with RSS in it, what I need to get is array of guid values, that is links to the post. This is what I have so far...

$xml = simplexml_load_file('http://lazhalazha.livejournal.com/data/rss');
foreach ($xml->channel->item as $item){
    print_r($item->guid);
}

Output is series of these objects

SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [isPermaLink] => true
        )

    [0] => http://lazhalazha.livejournal.com/713.html
)

Solved this by converting this object to string, then it's passing correct URL instead of object.

$xml = simplexml_load_file('http://lazhalazha.livejournal.com/data/rss');
$linkArray = array();
foreach ($xml->channel->item as $item){
    $guid = (string)$item->guid;
    array_push($linkArray, $guid);
}

<?php
$_temp = array();
$xml = simplexml_load_file('http://lazhalazha.livejournal.com/data/rss');

foreach ($xml->channel->item as $item){
    $_temp[] = (string)$item->guid[0];
}

print_r($_temp);
?>
