    return true;
  }else{
    return false;
  }
}
/**
 * 是否是GET提交的
 */
function isGet(){
  return $_SERVER['REQUEST_METHOD'] == 'GET' ? true : false;
}
/**
 * 是否是POST提交
 * @return int
 */
function isPost() {
  return ($_SERVER['REQUEST_METHOD'] == 'POST' && checkurlHash($GLOBALS['verify']) && (empty($_SERVER['HTTP_REFERER']) || preg_replace("~https?:\/\/([^\:\/]+).*~i", "\\1", $_SERVER['HTTP_REFERER']) == preg_replace("~([^\:]+).*~", "\\1", $_SERVER['HTTP_HOST']))) ? 1 : 0;
}
