function fetch_title($url)
{
    if (!preg_match('~^https?://~i', $url))
    {
        trigger_error('Invalid URL given in ' . __FUNCTION__, E_USER_NOTICE);
        return false;
    }

    if (!$content = @file_get_contents($url))
    {
        return false;
    }
    else if (!preg_match('~<title>(.*?)</title>~si', $content, $title))
    {
        return false;
    }

    return $title[1];
}
