Php - Showing youtube videos in a table

Question

I'm working with the youtube v3 api. After a few tests, I realized that I need some help. When I'm trying to display the xml content, I'm just getting null values. Can anybody help me?

If you want to see the xml:

https://www.youtube.com/feeds/videos.xml?channel_id=$channelid

And my code is:

$xml=simplexml_load_file("videos.xml");
foreach($xml as $content) { 
     echo $content->title . "<br>"; 
     echo $content->link['href'] . "<br>";

}

Xml that I want to display:

<entry>
Video ID <yt:videoId>Q4vSZA_8kYY</yt:videoId>
Video title <title>¡Trailer del canal! CBPrductions</title>

Upload date <published>2016-01-14T07:37:03+00:00</published>

You can user any id you want, for example =UCBR8-60-B28hp2BmDPdntcQ (YouTube Spotlight) — lluiscab, Jan 29 '16 at 15:01

I think you can register the namespace and use xpath. Then for the 'media' and the 'yt' you can get the children by passing the namespace.

If you want to display the first entry:

$url = 'https://www.youtube.com/feeds/videos.xml?channel_id=UCRGn72Qu0KTtI_ujNxRr3Fg';
$xml = simplexml_load_file($url);
$ns = $xml->getDocNamespaces(true);
$xml->registerXPathNamespace('a', 'http://www.w3.org/2005/Atom');
$elements = $xml->xpath('//a:entry');
$content = $elements[0];

$yt = $content->children('http://www.youtube.com/xml/schemas/2015');
$media = $content->children('http://search.yahoo.com/mrss/');
echo "Video ID: " . $yt->videoId . "<br>";
echo "Video title: " . $content->title . "<br>";
echo "Upload date: " . $content->published . "<br>";
echo "Description: " .$media->group->description . "<br>";

If you want to display the information from all the entries, you can use:

foreach ($elements as $content) {
    $yt = $content->children('http://www.youtube.com/xml/schemas/2015');
    $media = $content->children('http://search.yahoo.com/mrss/');
    echo "Video ID: " . $yt->videoId . "<br>";
    echo "Video title: " . $content->title . "<br>";
    echo "Upload date: " . $content->published . "<br>";
    echo "Description: " . $media->group->description . "<br>";
    echo "<br>";
}

Thanks a lot! But, one question, what's the 'use' of the youtube xml schemas, w3.org and yahoo links? — lluiscab, Jan 30 '16 at 11:59
Btw: for the thumbnail I have to do: $media->group->thumbnail['url'] ? — lluiscab, Jan 30 '16 at 12:23
@lluiscab For the thumbnail you can use: `$media->group->thumbnail->attributes()->url->__toString()` — The fourth bird, Jan 30 '16 at 12:55
Ok, another question XD If I echo the descirption, it's all in one line, how can I fix it? — lluiscab, Feb 02 '16 at 14:36
