PHP not displaying error or echo

Question

I have a PHP script that scrapes the meta tags and title from a webpage. It should echo them but instead does nothing. I've tried error_reporting(E_ALL) , ini_set('display_errors',1); , etc, but they do not provide any reasoning behind this.

function file_get_contents_curl($url)
{
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

    $data = curl_exec($ch);
    curl_close($ch);

    return $data;
}

$html = file_get_contents_curl("http://www.tomato.co.uk/");

$doc = new DOMDocument();
@$doc->loadHTML($html);
$nodes = $doc->getElementsByTagName('title');

$title = $nodes->item(0)->nodeValue;
echo $title;

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

for ($i = 0; $i < $metas->length; $i++)
{
    $meta = $metas->item($i);
    if($meta->getAttribute('name') == 'description')
        $description = $meta->getAttribute('content');
        echo $description;
    if($meta->getAttribute('name') == 'keywords')
        $keywords = $meta->getAttribute('content');
        echo $keywords;
}

Answer 1

Your script works for me:
