+
+;;; Commentary:
+
+;; This file is a forward-compatibility shim introduced while PHP Mode is
+;; being reworked to no longer depend on CC Mode.
+;;
+;; In the target design, the CC Mode based implementation is renamed to
+;; `php-cc-mode' and the name `php-mode' is reused for a cc-mode
+;; independent major mode.  During the transition `php-mode' (in
+;; php-mode.el) is still the CC Mode based implementation, so this file
+;; only establishes the *names* that code will migrate to, without
+;; changing any behavior:
+;;
+;;   - `php-cc-mode' is provided as an alias for `php-mode', so that
+;;     configuration or third-party code written against the new name
+;;     works now and keeps working after the eventual swap.
+;;   - Variable names that will belong to `php-cc-mode' are provided as
+;;     aliases of their current `php-mode-*' counterparts.
+;;
+;; Loading this file has no effect on `php-mode' itself: it does not
+;; register any `auto-mode-alist' / `interpreter-mode-alist' entry, and
+;; it does not redefine `php-mode'.  It is intentionally kept out of the
+;; `php-mode' require graph and is loaded only when something asks for
+;; `php-cc-mode'.
+
+;;; Code:
+

+already refer to the CC Mode based implementation by the name it will
+keep (`php-cc-mode') once the default `php-mode' becomes the cc-mode
+independent implementation.")
+
+;; Hook: configuration hung on `php-cc-mode-hook' should run for the CC
