" Vim indent file
" Language:	PHP

" URL:		https://www.2072productions.com/vim/indent/php.vim
" Home:		https://github.com/2072/PHP-Indenting-for-VIm
" Last Change:	2020 Mar 05
" Version:	1.70
"
"
"	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.com
"  ( 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 (https://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).
