Here you go:

class UrlToTitleConverter{

    public function convert($Url){
        $response = wp_remote_get($Url);
        if ( is_array( $response ) ) {
            $body = $response[\'body\'];
            $title = substr($body, strpos($body, \'<title>\')+7);
            $title = substr($title, 0, strpos($title, \'</title>\'));
        }
        return $title;
    }
}

试试这个

$tags    = get_meta_tags(\'http://www.bbc.com/news/technology-34527439\');
$title   = $tags[\'twitter:title\'];
$content = $tags[\'description\'];
$image   = $tags[\'twitter:image:src\'];

提供URL的输出。
