;;; 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.
