" Vim indent file
" Language: Php
" Author: Miles Lott
" URL: http://groupwhere.org/php.vim
" Last Change: 2002 Dec 16
" 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.
