+" Vim indent file
+" Language:	PHP
+" Author:	John Wellesz <John.wellesz (AT) teaser (DOT) fr>
+" URL:		http://www.2072productions.com/vim/indent/php.vim
+" Home:		https://github.com/2072/PHP-Indenting-for-VIm
+" Last Change:	2017 Jun 13
+" Version:	1.62
+"
+"
+"	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).

+"    Indenting keywords are based on Oracle and Sybase Adaptive Server
+"    Anywhere (ASA).  Test indenting was done with ASA stored procedures and
+"    fuctions and Oracle packages which contain stored procedures and
+"    functions.
+"    This has not been tested against Microsoft SQL Server or
+"    Sybase Adaptive Server Enterprise (ASE) which use the Transact-SQL
+"    syntax.  That syntax does not have end tags for IF's, which makes
+"    indenting more difficult.
+"
+" Known Issues:
+"    The Oracle MERGE statement does not have an end tag associated with
+"    it, this can leave the indent hanging to the right one too many.
+"
+" History:
+"    3.0 (Dec 2012)

+"    2.0
