;;; Usage

;; Rename this file to php-mode.el if it isn't already then place it in
;; your Emacs lisp path (eg. site-lisp) and add to your .emacs file:
;;   (require 'php-mode)

;; If you want colorization, turn on global-font-lock or
;; add this to your .emacs:
;;   (add-hook 'php-mode-user-hook 'turn-on-font-lock)

;; To use abbrev-mode, add lines like this:
;;   (add-hook 'php-mode-user-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

;;; Commentary:

;; PHP mode is a major mode for editing PHP 3 and 4 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.
