" Last Change: 2013 August 7th
" Version: 1.39
"
"
" Type :help php-indent for available options
"
" A fully commented version of this file is available on github
"
"
" If you find a bug, please open a ticket on github.org
" ( https://github.com/2072/PHP-Indenting-for-VIm/issues ) with an example of
" code that breaks the algorithm.
"
" NOTE: This script must be used with PHP syntax ON and with the php syntax
" script by Lutz Eymers (http://www.isp.de/data/php.vim ) or with the
" script by Peter Hodge (http://www.vim.org/scripts/script.php?script_id=1571 )
" the later is bunbdled by default with Vim 7.
"
"
" In the case you have syntax errors in your script such as HereDoc end
" identifiers not at col 1 you'll have to indent your file 2 times (This
" script will automatically put HereDoc end identifiers at col 1 if
" they are followed by a ';').
"
" NOTE: If you are editing files in Unix file format and that (by accident)
" there are '\r' before new lines, this script won't be able to proceed
" correctly and will make many mistakes because it won't be able to match
" '\s*$' correctly.
" So you have to remove those useless characters first with a command like:
"
" :%s /\r$//g
"
" or simply 'let' the option PHP_removeCRwhenUnix to 1 and the script will
" silently remove them when VIM load this script (at each bufread).
