- " Vim indent file
- " Language: Php
- " Author: Miles Lott <milos@groupwhere.org>
- " URL: http://groupwhere.org/php.vim
- " Last Change: 2003 May 11
- " Version: 0.3
- " Notes: Close all switches with default:\nbreak; and it will look better.
- " Also, open and close brackets should be alone on a line.
- " This is my preference, and the only way this will look nice.
- " Try an older version if you care less about the formatting of
- " switch/case. It is nearly perfect for anyone regardless of your
- " stance on brackets.
- "
- " Options php_noindent_switch=1 -- do not try to indent switch/case statements (version 0.1 behavior)

- " Only load this indent file when no other was loaded.
