Can't load php-mode on OS X

[diegueins680]

When I use the 2008 version of php-mode.el from the following link I don't have any issues, and Emacs color codes my php code correctly:

http://php-mode.sourceforge.net

However, when I replace php-mode.el with the current version, emacs displays the following error:

An error has ocurred while loading '~/.emacs':

File error: Cannot open load file, php-mode

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file. Start Emacs with the 
'--debug-init' option to view a complete error backtrace.

This is the output of doing such:

Debugger entered--Lisp error: (error "Invalid modifier in string")

Hey, I was just having the same problem, having copied my emacs configuration over from a linux box (with GNU emacs 23.3.1) to a Mac (with emacs 22.1.1).

Installing the latest release of php-mode (version 1.12) fixed it for me. The version I had previously installed was 1.10.

Thank you @akf for the information. Unfortunately I do not have access to a Mac for testing PHP Mode, so every bit of info like this is very useful to have.

I cannot reproduce this issue.

Mac users should not use /usr/bin/emacs. It is too old(22.1).
Most packages don't work on it.

It is easy to install newer Emacs via homebrew or macports.
I recommend mac users to use them.
