Here is the content from my .emacs file.

(add-hook 'php-mode-hook
        (lambda ()
        (c-set-style "bsd")
        (setq indent-tabs-mode t)
        (setq c-basic-offset 4)
        (setq tab-width 4)
        (c-set-offset 'arglist-close 'c-lineup-arglist-operators)
        (c-set-offset 'arglist-intro '+)
        (c-set-offset 'arglist-cont-nonempty 'c-lineup-math)
        (c-set-offset 'case-label '+)       
        ))

I want to move these formatting settings to the project specific directory. Although I can do it easily for setq statements (e.g. (setq indent-tabs-mode t)), I am not able to do it for function calls like: (c-set-offset 'arglist-intro '+).

Here is what I have put into my .dir-locals.el:

;;; Directory Local Variables
;;; See Info node `(emacs) Directory Variables' for more information.

    ((php-mode
        (c-set-style "bsd")
        (indent-tabs-mode . t)
        (c-basic-offset . 4)
        (tab-width . 4)
        (c-set-offset 'arglist-close 'c-lineup-arglist-operators)
        (c-set-offset 'arglist-intro 'c-basic-offset)
        (c-set-offset 'arglist-cont-nonempty 'c-lineup-math)
        (c-set-offset 'case-label '+)       
      ))

What is wrong here?
