I have setup web-mode and lsp mode for PHP programming in my config file. It is very minimal and flymake works perfectly.

I am struggling to find a way to get code formatting to work. I was told that I could install PHP_beautifier from Pear (which i did) and use it in emacs. But I am not sure how exactly?

There is no such package in emacs either.

My question is what is the best way to auto-format code on save with PHP?


(use-package lsp-mode
  :ensure t
  :config
  (setq lsp-headerline-breadcrumb-enable nil) ;; works
  (setq lsp-enable-symbol-highlighting nil) ;; works
  (setq lsp-signature-render-documentation nil)
  (setq lsp-completion-provider :none) ;; works
  (setq lsp-diagnostics-provider :flymake) ;; underline error
  )

(use-package web-mode
  :ensure t
  :init
  (setq web-mode-code-indent-offset 4)
  (setq web-mode-markup-indent-offset 4)
  (setq web-mode-enable-sql-detection t)

  )

Check whether web-mode-enable-auto-indentation is enabled. It should be so for GUI Emacs (not in terminal) by default. With this option enabled, buffer contents should be re-indented automatically.

Optionally, call M-x web-mode-buffer-indent (C-c TAB or C-c C-i and available from menu). For example, this way:

(defun my-web-mode-hook ()
  (add-hook 'after-save-hook #'web-mode-buffer-indent))

(add-hook 'web-mode-hook 'my-web-mode-hook)

The following part of the answer addresses the question(s) more generally.

It's quite typical to install php-mode for PHP programming language syntax highlighting and indentation. Whilst web-mode is more suitable for the scripts containing a mix of languages. If your case is the former, I'd suggest to use php-mode and install one of the PHP language servers for the mentioned lsp-mode to direct requests to.

Note, that since Emacs 29 built-in LSP client Eglot is provided, which also would still require installation of a language server.

Another thing to note, you might find tree-sitter usage useful (support for which is also built-in since Emacs 29).

  • Most of the time, my PHP code has PHP and HTML in the same file. Hence why I use web-mode. Unlike PPHP mode, it doesn't have a formatter.
