Getting meta title and description

I am having trouble getting the meta description/title from this specific site.

Here is some code:

$file = file('http://www.thegooddrugsguide.com/lsd/index.htm');
$file = implode("",$file);
if (preg_match('/<title>(.*?)<\/title>/is',$file,$t)) $title = $t[1];

It works with other sites, but not with the site in question. What could be the problem?

$url = "http://www.thegooddrugsguide.com/lsd/index.htm";    
$tags = get_meta_tags($url);
$description = $tags["description"];

This should work fine:

$doc = new DOMDocument;
$doc->loadHTMLFile('http://example.com');

$title = $doc->getElementsByTagName('title');
$title = $title[0];

$metas = $doc->getElementsByTagName('meta');

foreach ($metas as $meta) {
  if (strtolower($meta->getAttribute('name')) == 'description') {
    $description = $meta->getAttribute('value');
  }
}

Edit: this shorter version can also work to find the description:

$xpath = new DOMXPath($doc);
$description = $xpath->query('//meta[@name="description"]/@content');
