;;; 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
;; 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.

;;; Changelog:
;; 1.5
;; Support function keywords like public, private and the ampersand
;; character for function-based commands. Support abstract, final,
;; static, public, private and protected keywords in Imenu. Fix
;; reversed order of Imenu entries. Use font-lock-preprocessor-face
;; for PHP and ASP tags. Make php-mode-modified a literal value
;; rather than a computed string. Add date and time constants of
;; PHP. (Dias Badekas) Fix false syntax highlighting of keywords
;; because of underscore character. Change HTML indentation warning
;; to match only HTML at the beginning of the line. Fix
;; byte-compiler warnings. Clean-up whitespace and audited style
;; consistency of code. Remove conditional bindings and XEmacs code
;; that likely does nothing.
;; 1.4
;; Updated GNU GPL to version 3. Ported to Emacs 22 (CC mode
;; 5.31). M-x php-mode-version shows version. Provide end-of-defun
;; beginning-of-defun functionality. Support add-log library.
;; Fix __CLASS__ constant (Ian Eure). Allow imenu to see visibility
;; declarations -- "private", "public", "protected". (Bill Lovett)
;; 1.3
;; Changed the definition of # using a tip from Stefan
;; Monnier to correct highlighting and indentation. (Lennart Borgman)
;; Changed the highlighting of the HTML part. (Lennart Borgman)
;; See the ChangeLog file included with the source package.
