;;; Commentary:
;; PHP Mode is a major mode for editing PHP source code. It's an
;; extension of C mode; thus it inherits all C mode's navigation
;; functionality. But it colors according to the PHP grammar and
;; indents according to the PEAR coding guidelines. It also includes
;; a couple handy IDE-type features such as documentation search and a
;; source and class browser.
;; ## Usage
;; Put this file in your Emacs Lisp path (eg. site-lisp) and add to
;; your .emacs file:
;; (require 'php-mode)
;; To use abbrev-mode, add lines like this:
;; (add-hook 'php-mode-hook
;; '(lambda () (define-abbrev php-mode-abbrev-table "ex" "extends")))
;; To make php-mode compatible with html-mode, see http://php-mode.sf.net
;; Many options available under Help:Customize
;; Options specific to php-mode are in
;; Programming/Languages/PHP
;; Since it inherits much functionality from c-mode, look there too
;; Programming/Languages/C
;;; Code:
(require 'cc-mode)
(require 'cc-langs)
(eval-when-compile
(require 'cc-fonts))
;; Boilerplate from other `cc-mode' derived modes. See
;; http://cc-mode.sourceforge.net/derived-mode-ex.el for details on how this all
;; fits together.
