vim 代码规范工具php-cs-fixer.phar
(參考https://github.com/FriendsOfPHP/PHP-CS-Fixer)
INSTALL

curl http://get.sensiolabs.org/php-cs-fixer.phar -o php-cs-fixer
  sudo chmod a+x php-cs-fixer
  sudo mv php-cs-fixer /usr/local/bin/php-cs-fixer

至此，你能够直接用php-cs-fixer格式化代码了

USAGE

(眼下支持的level有psr0, psr1, psr2,symfony，contrib)

  php-cs-fixer fix test.php --level=psr2
   php-cs-fixer fix ./ --level=psr2

这并不能满足一个vimer的小心灵

vim-php-cs-fixer
INSTALL

Bundle 'stephpy/vim-php-cs-fixer

CONFIGURE
.vimrc(參考：https://github.com/stephpy/vim-php-cs-fixer)

" If php-cs-fixer is in $PATH, you don't need to define line below
" let g:php_cs_fixer_path = "~/php-cs-fixer.phar" " define the path to the php-cs-fixer.phar
let g:php_cs_fixer_level = "psr2"              " which level ?(psr0, psr1, psr2, symfony)
let g:php_cs_fixer_config = "default"             " configuration
let g:php_cs_fixer_php_path = "php"               " Path to PHP
" If you want to define specific fixers:
"let g:php_cs_fixer_fixers_list = "linefeed,short_tag,indentation"
let g:php_cs_fixer_enable_default_mapping = 1     " Enable the mapping by default (<leader>pcd)
let g:php_cs_fixer_dry_run = 0                    " Call command with dry-run option
let g:php_cs_fixer_verbose = 0                    " Return the output of command if 1, else an inline information.

以上配置我们发现

let g:php_cs_fixer_enable_default_mapping = 1     " Enable the mapping by default (<leader>pcd)

这个配置快捷键为\pcd 实际操作中会发现极易出错，并且太长了吧
.vim/bundle/vim-php-cs-fixer/plugin/php-cs-fixer.vim

if(g:php_cs_fixer_enable_default_mapping == 1)
    nnoremap <silent><leader>pcd :call PhpCsFixerFixDirectory()<CR>
    nnoremap <silent><leader>pcf :call PhpCsFixerFixFile()<CR>
endif

能够发现
pcd是格式化文件夹
pcf是格式化文件
如今能够把pcd。和pcf换成自己喜欢的快捷键了

ps:是nomal模式，是一个快捷键的前缀默认是\，可在vim中用map命令查看
