PHP Coding Standards Fixer

The PHP Coding Standards Fixer tool fixes most issues in your code when you want to follow the PHP coding standards as defined in the PSR-1 and PSR-2 documents.

If you are already using PHP_CodeSniffer to identify coding standards problems in your code, you know that fixing them by hand is tedious, especially on large projects. This tool does the job for you.

Requirements

PHP needs to be a minimum version of PHP 5.3.6.

Installation

Locally

Download the php-cs-fixer.phar file and store it somewhere on your computer.

Globally (manual)

You can run these commands to easily access php-cs-fixer from anywhere on your system:

$ wget http://get.sensiolabs.org/php-cs-fixer.phar -O php-cs-fixer

or with curl:

$ curl http://get.sensiolabs.org/php-cs-fixer.phar -o php-cs-fixer

then:

$ sudo chmod a+x php-cs-fixer
$ sudo mv php-cs-fixer /usr/local/bin/php-cs-fixer

Then, just run php-cs-fixer.

Globally (Composer)

To install PHP-CS-Fixer, install Composer and issue the following command:

$ ./composer.phar global require fabpot/php-cs-fixer

Then, make sure you have ~/.composer/vendor/bin in your PATH, and you're good to go:

export PATH="$PATH:$HOME/.composer/vendor/bin"

Globally (homebrew)

PHP-CS-Fixer is part of the homebrew-php project. Follow the installation instructions at https://github.com/homebrew/homebrew-php if you don't already have it.

$ brew install homebrew/php/php-cs-fixer

Update

Locally

The self-update command tries to update php-cs-fixer itself:

$ php php-cs-fixer.phar self-update

Globally (manual)

You can update php-cs-fixer through this command:

$ sudo php-cs-fixer self-update

Globally (Composer)

You can update php-cs-fixer through this command:

$ ./composer.phar global update fabpot/php-cs-fixer

Globally (homebrew)

You can update php-cs-fixer through this command:

$ brew upgrade php-cs-fixer

Usage

The fix command tries to fix as much coding standards problems as possible on a given file or directory:

php php-cs-fixer.phar fix /path/to/dir
php php-cs-fixer.phar fix /path/to/file

The --verbose option show applied fixers. When using txt format (default one) it will also displays progress notification.

The --level option limits the fixers to apply on the project:

php php-cs-fixer.phar fix /path/to/project --level=psr0
php php-cs-fixer.phar fix /path/to/project --level=psr1
php php-cs-fixer.phar fix /path/to/project --level=psr2
php php-cs-fixer.phar fix /path/to/project --level=symfony

By default, all PSR-2 fixers and some additional ones are run. The "contrib level" fixers cannot be enabled via this option; you should instead set them manually by their name via the --fixers option.

The --fixers option lets you choose the exact fixers to apply (the fixer names must be separated by a comma):

php php-cs-fixer.phar fix /path/to/dir --fixers=linefeed,short_tag,indentation

You can also blacklist the fixers you don't want by placing a dash in front of the fixer name, if this is more convenient, using -name_of_fixer:

php php-cs-fixer.phar fix /path/to/dir --fixers=-short_tag,-indentation

When using combination with exact and blacklist fixers, apply exact fixers along with above blacklisted result:

php php-cs-fixer.phar fix /path/to/dir --fixers=linefeed,-short_tag

A combination of --dry-run and --diff will display summary of proposed fixes, leaving your files unchanged.

The command can also read from standard input, in which case it won't automatically fix anything:

cat foo.php | php php-cs-fixer.phar fix --diff -

The --config option customizes the files to analyse, based on some well-known directory structures:

# For the Symfony 2.3+ branch
php php-cs-fixer.phar fix /path/to/sf23 --config=sf23

Choose from the list of available configurations:

default A default configuration
magento The configuration for a Magento application
sf23 The configuration for the Symfony 2.3+ branch

The --dry-run option displays the files that need to be fixed but without actually modifying them:

php php-cs-fixer.phar fix /path/to/code --dry-run

Instead of using command line options to customize the fixer, you can save the configuration in a .php_cs file in the root directory of your project. The file must return an instance of Symfony\CS\ConfigInterface, which lets you configure the fixers, the level, the files, and directories that need to be analyzed. The example below will add two contrib fixers to the default list of symfony-level fixers:

<?php

$finder = Symfony\CS\Finder\DefaultFinder::create()
    ->exclude('somedir')
    ->in(__DIR__)
;

return Symfony\CS\Config\Config::create()
    ->fixers(array('strict_param', 'short_array_syntax'))
    ->finder($finder)
;

If you want complete control over which fixers you use, you may use the empty level and then specify all fixers to be used:

<?php

$finder = Symfony\CS\Finder\DefaultFinder::create()
    ->in(__DIR__)
;

return Symfony\CS\Config\Config::create()
    ->level(Symfony\CS\FixerInterface::NONE_LEVEL)
    ->fixers(array('trailing_spaces', 'encoding'))
    ->finder($finder)
;

You may also use a blacklist for the Fixers instead of the above shown whitelist approach. The following example shows how to use all symfony Fixers but the psr0 fixer. Note the additional - in front of the Fixer name.

<?php

$finder = Symfony\CS\Finder\DefaultFinder::create()
    ->exclude('somedir')
    ->in(__DIR__)
;

return Symfony\CS\Config\Config::create()
    ->fixers(array('-psr0'))
    ->finder($finder)
;

The symfony level is set by default, you can also change the default level:

<?php

return Symfony\CS\Config\Config::create()
    ->level(Symfony\CS\FixerInterface::PSR2_LEVEL)
;

In combination with these config and command line options, you can choose various usage.

For example, default level is symfony, but if you also don't want to use the psr0 fixer, you can specify the --fixers="-psr0" option.

But if you use the --fixers option with only exact fixers, only those exact fixers are enabled whether or not level is set.

With the --config-file option you can specify the path to the .php_cs file.

Caching

You can enable caching by returning a custom config with caching enabled. This will speed up further runs.

<?php

return Symfony\CS\Config\Config::create()
    ->setUsingCache(true)
;

Helpers

Dedicated plugins exist for:

Contribute

The tool comes with quite a few built-in fixers and finders, but everyone is more than welcome to contribute more of them.

Fixers

A fixer is a class that tries to fix one CS issue (a Fixer class must implement FixerInterface).

Configs

A config knows about the CS level and the files and directories that must be scanned by the tool when run in the directory of your project. It is useful for projects that follow a well-known directory structures (like for Symfony projects for instance).
