如何在Emacs中关闭php-indent警告

Warning (php-indent):
        Indentation fails badly with mixed HTML and PHP.
        Look for an Emacs Lisp library that supports "multiple
        major modes" like mumamo,mmm-mode or multi-mode.

它出现在我wiindow的底部,占据了我编辑屏幕的一半.我怎么关掉这个？

我知道你可以添加各种“附加组件”和模式,以使Emacs格式化PHP HTML,但我只想关闭警告.我怎么能这样做？

编辑：

这是php-mode.el文件的一部分,其中上述错误似乎来自：

(defvar php-completion-table nil
  "Obarray of tag names defined in current tags table and functions know to PHP.")

(defvar php-warned-bad-indent nil)
(make-variable-buffer-local 'php-warned-bad-indent)

;; Do it but tell it is not good if html tags in buffer.
(defun php-check-html-for-indentation ()
  (let ((html-tag-re "</?sw+.*?>")
        (here (point)))
    (if (not (or (re-search-forward html-tag-re (line-end-position) t)
                 (re-search-backward html-tag-re (line-beginning-position) t)))
        t
      (goto-char here)
      (setq php-warned-bad-indent t)
      (lwarn 'php-indent :warning
