🚧 Work in Progress! 🚧

Prettier PHP Plugin

WORK IN PROGRESS

Please note that this plugin is currently in alpha stage and still under active development. We encourage everyone to try it and give feedback, but we don't recommend it for production use yet.

Intro

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.

This plugin adds support for the PHP language to Prettier.

Input

array_map(function($arg1,$arg2) use ( $var1, $var2 ) {
    return $arg1+$arg2/($var+$var2);
}, array("complex"=>"code","with"=>"inconsistent","formatting"=>"is", "hard" => "to", "maintain"=>true));

Output

array_map(
    function ($arg1, $arg2) use ($var1, $var2) {
        return $arg1 + $arg2 / ($var + $var2);
    },
    array(
        "complex" => "code",
        "with" => "inconsistent",
        "formatting" => "is",
        "hard" => "to",
        "maintain" => true
    )
);

Playground

You can give the plugin a try in our playground!

Install

yarn:

yarn add --dev prettier @prettier/plugin-php
# or globally
yarn global add prettier @prettier/plugin-php

npm:

npm install --save-dev prettier @prettier/plugin-php
# or globally
npm install --global prettier @prettier/plugin-php

Use

With Node.js

If you installed prettier as a local dependency, you can add prettier as a script in your package.json,

{
  "scripts": {
    "prettier": "prettier"
  }
}

and then run it via

yarn run prettier path/to/file.php --write
# or
npm run prettier -- path/to/file.php --write

If you installed globally, run

prettier path/to/file.php --write

In the Browser

This package exposes a standalone.js that can be used alongside Prettier's own standalone.js to make the PHP plugin work in browsers without a compile step.

First, grab both standalone scripts from an npm CDN like unpkg:

<script src="https://unpkg.com/prettier/standalone.js"></script>
<script src="https://unpkg.com/@prettier/plugin-php/standalone.js"></script>

Then use Prettier with PHP, just like this:

prettier.format(YOUR_CODE, {
  plugins: prettierPlugins,
  parser: "php"
});

See this code in action in this basic demo.

With Bundlers

Bundlers like webpack, Rollup or browserify automatically recognize how to handle the PHP plugin. Remember that even when using a bundler, you still have to use the standalone builds:

import prettier from "prettier/standalone";
import phpPlugin from "@prettier/plugin-php/standalone";

prettier.format(YOUR_CODE, {
  plugins: [phpPlugin],
  parser: "php"
});

Configuration

Prettier for PHP supports the following options:

Name	Default	Description
printWidth	80	Same as in Prettier (see prettier docs)
tabWidth	4	Same as in Prettier (see prettier docs)
useTabs	false	Same as in Prettier (see prettier docs)
singleQuote	false	If set to "true", strings that use double quotes but do not rely on the features they add, will be reformatted. Example: "foo" -> 'foo', "foo $bar" -> "foo $bar".
trailingCommaPHP	"none"	If set to "all", trailing commas will be added wherever possible. If set to "php7.3", trailing commas will be added to multiline arrays, lists, uses and function calls. If set to "php7.2", trailing commas will be added to multiline arrays, lists and uses. If set to "php5", trailing commas will be added to multiline arrays and lists. if set to "none", no trailing commas.
braceStyle	"psr-2"	If set to "psr-2", prettier will move open brace for code blocks (classes, functions and methods) onto new line. If set to "1tbs", prettier will move open brace for code blocks (classes, functions and methods) onto same line.
requirePragma	false	Same as in Prettier (see prettier docs)
insertPragma	false	Same as in Prettier (see prettier docs)

Editor integration

Atom

The official prettier plugin for atom supports plugins.

VScode

The official prettier plugin for vscode supports plugins since Version 1.10.0. To enable it, install the extension and make sure the plugin is installed locally (in your project folder). After restarting VScode the plugin should work as expected.

Sublime Text

Sublime Text support is available through Package Control and the JsPrettier plugin.

Vim

Regarding plugin support in the official plugin vim-prettier see this issue.

ALE

The linting plugin ALE has built-in support for prettier and its plugins. Just add prettier to your list of fixers. For example:

let g:ale_fixers={
  \'javascript': ['prettier'],
  \'json': ['prettier'],
  \'php': ['prettier'],
\}

Custom

Alternatively, adding the following to .vimrc will define a custom command :PrettierPhp that runs the plugin while preserving the cursor position and run it on save.

" Prettier for PHP
function PrettierPhpCursor()
  let save_pos = getpos(".")
  %! prettier --stdin --parser=php
  call setpos('.', save_pos)
endfunction
" define custom command
command PrettierPhp call PrettierPhpCursor()
" format on save
autocmd BufwritePre *.php PrettierPhp
