;;; Usage

;; Place this file in your Emacs lisp path (eg. site-lisp)
;; and add to your .emacs file:
;;   (load-library "php-mode-102")

;; 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 make php-mode compatible with html-mode, see 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.


;;; Changelog:

;; 1.02
;;   Highlight HTML tags and entities (see site for more on HTML)
;;   Highlight more constants by default
;;   Fixed problem with $-line indenting inside switch (see comments)
;;   Fix to show keymap in help mode (Ryan Sammartino)
;;   Added .phps to default extensions to match (John Keller)

;; 1.0.1
;;   Fix for some speedbar problems

;; 1.0.0
;;   Function indentation fix (Craig Andrews)
;;   Added option to open speedbar on buffer load
;;   Fixed PEAR filename matching regexps and bug with mmm-mode
;;   Added preference option to always use PEAR standards
;;   Fixed PEAR hook bug with XEmacs
;;   Took out warning for empty parens in "new Object()"
;;   Fixed keyword highlighting of 'this' at start of variable
;;   Removed "goto" references
;;   Added 'next' as keyword

;; 0.9.9
;;   Fixed highlights for targets of gotos and 'default' within a switch
;;   Changed my e-mail and URL to SourceForge
;;   Changed name of hook variable (update your .emacs)
;;   Wrapped PEAR standards into a PEAR hook
;;   Disabled coloring non-core constants (see comments to re-enable)

;; 0.9.8
;;   Thanks to a patch from Stig Saether Bakken:
;;   Checks for PEAR before setting indent-tabs-mode to nil
;;   Adds some keywords that got lost
;;   Highlights function $foo and class::method
;;   Removes C++ template from speedbar search expression :)
;;   Adds about a thousand constants
;;     So many that if you want to recompile php-mode-098.el
;;     you'll have to greatly increase max-specpdl-size

;; 0.9.7
;;      This version marks a huge advance and will become 1.0.0
;;    after I wait a bit for possible bug reports.
;;      
;;      The primary improvement is support for shell-style comments
;;    in both GNU Emacs and XEmacs.  Thank for this goes to Fred
;;    Yankowski <fred@ontosys.com>.
