Youtube get video title from id

I understand this may have been answered somewhere, but after looking and looking through numerous questions/answers and other websites, I'm unable to find a suitable answer.

I'm trying to create a page, which will show some video from Youtube. It will show the image, and title. I've managed to do both of these, although i'm having problems with the title. With the code i'm using, it is awfully slow at loading. I assume because of it loading the actual website just to get the title.

This is what i'm using to get the titles currently.

function get_youtube_id($url){
    parse_str( parse_url( $url, PHP_URL_QUERY ), $my_array_of_vars );
    return $my_array_of_vars['v']; 
}
function get_youtube_title($video_id){
$url = "http://www.youtube.com/watch?v=".$video_id;

$page = file_get_contents($url);
$doc = new DOMDocument();
$doc->loadHTML($page);

$title_div = $doc->getElementById('eow-title');
$title = $title_div->nodeValue;

return $title;

}

So, how would the best way to get a youtube title by the id. The code I have does work, but it also makes the page load very very slow.

Thanks

It's been 5 years, but my script bellow could be useful.

<?php 

$ch = curl_init();


curl_setopt($ch, CURLOPT_URL, "https://www.youtube.com/watch?v=YOUTUBEID");
        
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$output = curl_exec($ch);

$document = htmlspecialchars($output);
curl_close($ch);     
        
$line = explode("\n", $document);
$judul = "";
foreach($line as $strline){
      preg_match('/\&lt;title\&gt;(.*?)\&lt;\/title\&gt;/s', $strline, $hasil);
      if (!isset($hasil[0]) || $hasil[0] == "") continue;
            $title =  str_replace(array("&lt;title&gt;", "&lt;/title&gt;"), "", $hasil[0]);
}
        
echo $title;

Here is a simple way to do it using PHP and no library. YouTube already allows you to retrieve video detail information in the JSON format, so all you need is a simple function like this:

   function get_youtube_title($ref) {
      $json = file_get_contents('http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=' . $ref . '&format=json'); //get JSON video details
      $details = json_decode($json, true); //parse the JSON into an array
      return $details['title']; //return the video title
    }

The function parameter being the video ID. You could also add a second parameter asking for a specific detail and change the function name so you could retrieve any data from the JSON that you would like.

EDIT:

If you would like to retrieve any piece of information from the returned video details you could use this function:

function get_youtube_details($ref, $detail) {
    if (!isset($GLOBALS['youtube_details'][$ref])) {
        $json = file_get_contents('http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=' . $ref . '&format=json'); //get JSON video details
        $GLOBALS['youtube_details'][$ref] = json_decode($json, true); //parse the JSON into an array
    }

    return $GLOBALS['youtube_details'][$ref][$detail]; //return the requested video detail
}

If you request different details about the same video, the returned JSON data is stored in the $GLOBALS array to prevent necessary calls to file_get_contents.

Also, allow_url_fopen will have to be on in your php.ini for file_get_contents to work, which may be a problem on shared hosts.
