Get YouTube video title with video ID in PHP

Question

I have to get the YouTube video title with the YouTube video ID in PHP.

Currently I am doing it like this:

    $html = "http://www.youtube.com/watch?v=" . $video_id;
    $doc = new DOMDocument();
    $doc->loadHTMLFile($html);
    $doc->preserveWhiteSpace = false;
    $title_div = $doc->getElementById('eow-title');
    $title = $title_div->nodeValue;

But this is throwing an error as:

Warning: DOMDocument::loadHTMLFile(http://www.youtube.com/watch?v=hMpCsfvi_3c): failed to open stream: HTTP request failed! HTTP/1.0 429 Too Many Requests in /home/vhosts/xxxx/xxxx/get_youtube_title.php on line 6

Warning: DOMDocument::loadHTMLFile(): I/O warning : failed to load external entity "http://www.youtube.com/watch?v=hMpCsfvi_3c" in /home/vhosts/xxxx/xxxx/get_youtube_title.php on line 6

The above method works fine on GoDaddy hosting, but not on 101domain.com hosting.

Another method I have tried is this:

if($content = file_get_contents("http://youtube.com/get_video_info?video_id=" . $video_id)) {
    parse_str($content, $ytarr);
    $myvideos[$i]['video_title'] = $ytarr['title'];
}
else
    $myvideos[$i]['video_title'] = "No title";

This throws an error as:

Warning: DOMDocument::loadHTMLFile(http://youtube.com/get_video_info?video_id=hMpCsfvi_3c): failed to open stream: HTTP request failed! HTTP/1.0 402 Payment Required in /home/vhosts/xxxx/get_youtube_title.php on line 6

Warning: DOMDocument::loadHTMLFile(): I/O warning : failed to load external entity "http://youtube.com/get_video_info?video_id=hMpCsfvi_3c" in /home/vhosts/xxxx/get_youtube_title.php on line 6

The last method I tried was this:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://youtube.com/get_video_info? video_id=" . $video_id);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

This doesn't throw any error, but it doesn't work either. The error reporting is E_ALL and display_errors is set to 1.

Somebody has told me it's safer to use the YouTube API for this. Since I am new to YouTube API, I need some help.

How can I get the video title with the video ID in PHP? Also an easy-to-follow tutorial for the YouTube API.

Answer 1

I got it working with file_get_contents(), but I used a different URL this time.

The URL I used was:

https://www.googleapis.com/youtube/v3/videos?id=' . $video_id . '&key=' . $YoutubeAPIKey . '&part=snippet

For example:

function get_youtube_title($video_id){
    $html = 'https://www.googleapis.com/youtube/v3/videos?id=' . $video_id . '&key=alskdfhwueoriwaksjdfnzxcvxzfserwesfasdfs&part=snippet';
    $response = file_get_contents($html);
    $decoded = json_decode($response, true);
    foreach ($decoded['items'] as $items) {
         $title = $items['snippet']['title'];
         return $title;
    }
}
echo $title = get_youtube_title('PQqudiUdGuo');
