php.vim

An up-to-date Vim syntax for PHP.

This project is a fork of php.vim--Garvin which in turn is an update of the php.vim script which in turn is an updated version of the php.vim syntax file distributed with Vim. Whew!

Installation

If you don't have a preferred installation method, vim-plug is quick and simple. With vim-plug installed, add the following to your vimrc (if you are a NeoVim user, see the FAQ page for help):

Plug 'StanAngeloff/php.vim'

Configuration

php.vim comes with sensible defaults for most use cases. Below is a list of some interesting configuration options you may tweak. Refer to the source code for additional options.

  • g:php_syntax_extensions_enabled, g:php_syntax_extensions_disabled
    b:php_syntax_extensions_enabled, b:php_syntax_extensions_disabled

    Default: g:php_syntax_extensions_enabled = ["bcmath", "bz2", "core", "curl", "date", "dom", "ereg", "gd", "gettext", "hash", "iconv", "json", "libxml", "mbstring", "mcrypt", "mhash", "mysql", "mysqli", "openssl", "pcre", "pdo", "pgsql", "phar", "reflection", "session", "simplexml", "soap", "sockets", "spl", "sqlite3", "standard", "tokenizer", "wddx", "xml", "xmlreader", "xmlwriter", "zip", "zlib"]

    A list of PHP extension names (lowercase) for which highlighting of built-in functions, constants, classes and interfaces is enabled / disabled.

    If you are not interested in highlighting any built-in functions/constants/etc., set g:php_syntax_extensions_enabled to an empty list [].

    If you are not interested in highlighting built-in functions/constants/etc. for a subset of PHP extensions, set g:php_syntax_extensions_enabled to a list of extensions you wish to disable, e.g., ["mcrypt"].

  • php_var_selector_is_identifier

    Default: 0

    Set this to a truthy value (e.g., 1) to include the dollar sign $ as part of the highlighting group for a PHP variable.

  • php_html_load, php_html_in_heredoc, php_html_in_nowdoc

    Default: 1 (NOTE: setting php_html_load to a truthy value takes precedence and overrides both php_html_in_heredoc & php_html_in_nowdoc)

    Set to a falsy value (e.g., 0) to disable embedding HTML in PHP. Doing so may yield significant speed-ups of syntax highlighting.

    This should not affect HTML highlighting in templating languages, such as Blade.

  • php_sql_query, php_sql_heredoc, php_sql_nowdoc

    Default: 1

    Set to a falsy value (e.g., 0) to disable SQL syntax in PHP. Doing so may yield moderate speed-ups of syntax highlighting.

Projects of interest

php.vim pairs nicely with:

Overriding highlighting

Syntax highlighting can be controlled at a fine-grained level. For example, all text in PHP comments is highlighted as phpComment by default, however there are smaller syntax groups you can tweak, e.g., how PHPDoc @tags appear. There are several syntax groups you can choose from.

Example: Overriding PHP @tags and $parameters in comments to appear as a different highlighting group, giving them distinct colouring:

" Put this function at the very end of your vimrc file.

function! PhpSyntaxOverride()
  " Put snippet overrides in this function.
  hi! link phpDocTags phpDefine
  hi! link phpDocParam phpType
endfunction

augroup phpSyntaxOverride
  autocmd!
  autocmd FileType php call PhpSyntaxOverride()
augroup END

Snippets

You may add the code snippets below to your PhpSyntaxOverride function (see above for instructions on how to create this function).

Colourising namespace separator in use, extends and implements

If you wish to highlight the namespace separator \ differently (original request):

hi phpUseNamespaceSeparator guifg=#808080 guibg=NONE gui=NONE
hi phpClassNamespaceSeparator guifg=#808080 guibg=NONE gui=NONE
Colourising parentheses

If you wish to highlight ( and ) differently (original request):

syn match phpParentOnly "[()]" contained containedin=phpParent
hi phpParentOnly guifg=#f08080 guibg=NONE gui=NONE

Developing

When you install php.vim using your preferred installation method, all the needed files are already in place.

If you have a more recent version of PHP installed locally (with all of the PHP extensions you want/need), you may use the provided Dockerfile to rebuild the syntax file:

docker build -t stanangeloff/php.vim --no-cache --force-rm .
docker run --rm -i -v "$PWD":/var/php -t stanangeloff/php.vim > /tmp/php.vim && cat /tmp/php.vim | sed 's/\x0D$//' > syntax/php.vim
docker rmi stanangeloff/php.vim

NOTE: The sed command strips out Windows line endings. If the updated syntax file fails to load and is corrupted, try loading syntax/php.vim in your favourite editor and ensure line endings are set to Unix.
