如何使用PHP - YouTube API从XML文件中检索内容

Question

Please help in using PHP and XML in retrieving dynamic content.

I have this code:

function yt_name() {
$xmlData = file_get_contents( 'http://gdata.youtube.com/feeds/api/users/youtube/uploads?max-results=5&prettyprint=true' ); 
$xml = new SimpleXMLElement($xmlData); 
$yt_name = $xml->event->name;

    echo $yt_name;

}

How can I retrieve the content inside <name>content</name> ?

Regards,

Thank you!

Answer 1

Once inside the object, you can retrieve childs by object index (node name):

function yt_name() {
    $xmlData = file_get_contents( 'http://gdata.youtube.com/feeds/api/users/youtube/uploads?max-results=5&prettyprint=true' ); 
    $xml = new SimpleXMLElement($xmlData); 
    return $xml;
}

$yt = yt_name();
echo $yt->author->name;

Output: YouTube Spotlight
