The PHP Coding Standards Fixer (PHP CS Fixer) tool fixes your code to follow standards; whether you want to follow PHP coding standards as defined in the PSR-1, PSR-2, etc., or other community driven ones like the Symfony one. You can also define your (teams) style through configuration.
It can modernize your code (like converting the pow function to the ** operator on PHP 5.6) and (micro) optimize it.
If you are already using a linter to identify coding standards problems in your code, you know that fixing them by hand is tedious, especially on large projects. This tool does not only detect them, but also fixes them for you.
The PHP CS Fixer is maintained on GitHub at https://github.com/FriendsOfPHP/PHP-CS-Fixer bug reports and ideas about new features are welcome there.
You can talk to us at https://gitter.im/PHP-CS-Fixer/Lobby about the project, configuration, possible improvements, ideas and questions, please visit us!
PHP needs to be a minimum version of PHP 5.6.0.
Download the php-cs-fixer.phar file and store it somewhere on your computer.
You can run these commands to easily access latest php-cs-fixer
from anywhere on
your system:
$ wget http://cs.sensiolabs.org/download/php-cs-fixer-v2.phar -O php-cs-fixer
or with specified version:
$ wget https://github.com/FriendsOfPHP/PHP-CS-Fixer/releases/download/v2.8.4/php-cs-fixer.phar -O php-cs-fixer
or with curl:
$ curl -L http://cs.sensiolabs.org/download/php-cs-fixer-v2.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
.
To install PHP CS Fixer, install Composer and issue the following command:
$ composer global require friendsofphp/php-cs-fixer
Then make sure you have the global Composer binaries directory in your PATH
. This directory is platform-dependent, see Composer documentation for details. Example for some Unix systems:
$ export PATH="$PATH:$HOME/.composer/vendor/bin"
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
The self-update
command tries to update php-cs-fixer
itself:
$ php php-cs-fixer.phar self-update
You can update php-cs-fixer
through this command:
$ sudo php-cs-fixer self-update
You can update php-cs-fixer
through this command:
$ ./composer.phar global update friendsofphp/php-cs-fixer
You can update php-cs-fixer
through this command:
$ brew upgrade php-cs-fixer
The fix
command tries to fix as much coding standards
problems as possible on a given file or files in a given directory and its subdirectories:
$ php php-cs-fixer.phar fix /path/to/dir
$ php php-cs-fixer.phar fix /path/to/file
By default --path-mode
is set to override
, which means, that if you specify the path to a file or a directory via
command arguments, then the paths provided to a Finder
in config file will be ignored. You can use --path-mode=intersection
to merge paths from the config file and from the argument:
$ php php-cs-fixer.phar fix --path-mode=intersection /path/to/dir
The --format
option for the output format. Supported formats are txt
(default one), json
, xml
, checkstyle
and junit
.
NOTE: the output for the following formats are generated in accordance with XML schemas
junit
follows the JUnit xml schema from Jenkinscheckstyle
follows the common "checkstyle" xml schema
The --verbose
option will show the applied rules. When using the txt
format it will also displays progress notifications.
The --rules
option limits the rules to apply on the
project:
$ php php-cs-fixer.phar fix /path/to/project --rules=@PSR2
By default the PSR1 and PSR2 rules are used.
The --rules
option lets you choose the exact rules to
apply (the rule names must be separated by a comma):
$ php php-cs-fixer.phar fix /path/to/dir --rules=line_ending,full_opening_tag,indentation_type
You can also blacklist the rules you don't want by placing a dash in front of the rule name, if this is more convenient,
using -name_of_fixer
:
$ php php-cs-fixer.phar fix /path/to/dir --rules=-full_opening_tag,-indentation_type
When using combinations of exact and blacklist rules, applying exact rules along with above blacklisted results:
$ php php-cs-fixer.phar fix /path/to/project --rules=@Symfony,-@PSR1,-blank_line_before_statement,strict_comparison
Complete configuration for rules can be supplied using a json
formatted string.
$ php php-cs-fixer.phar fix /path/to/project --rules='{"concat_space": {"spacing": "none"}}'
The --dry-run
flag will run the fixer without making changes to your files.
The --diff
flag can be used to let the fixer output all the changes it makes.
The --diff-format
option allows to specify in which format the fixer should output the changes it makes:
udiff
: unified diff format;sbd
: Sebastianbergmann/diff format (default when using --diff without specifying diff-format).
The --allow-risky
option (pass yes
or no
) allows you to set whether risky rules may run. Default value is taken from config file.
Risky rule is a rule, which could change code behaviour. By default no risky rules are run.
The --stop-on-violation
flag stops the execution upon first file that needs to be fixed.
The --show-progress
option allows you to choose the way process progress is rendered:
none
: disables progress output;run-in
: simple single-line progress output;estimating
: multiline progress output with number of files and percentage on each line. Note that with this option, the files list is evaluated before processing to get the total number of files and then kept in memory to avoid using the file iterator twice. This has an impact on memory usage so using this option is not recommended on very large projects;estimating-max
: same asestimating
but using all terminal columns instead of default 80.
If the option is not provided, it defaults to run-in
unless a config file that disables output is used, in which case it defaults to none
. This option has no effect if the verbosity of the command is less than verbose
.
$ php php-cs-fixer.phar fix --verbose --show-progress=estimating
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 -
Finally, if you don't need BC kept on CLI level, you might use PHP_CS_FIXER_FUTURE_MODE to start using options that would be default in next MAJOR release (unified differ, estimating, full-width progress indicator):
$ PHP_CS_FIXER_FUTURE_MODE=1 php php-cs-fixer.phar fix -v --diff

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 rule, you can save the
project configuration in a .php_cs.dist
file in the root directory of your project.
The file must return an instance of PhpCsFixer\ConfigInterface
which lets you configure the rules, the files and directories that
need to be analyzed. You may also create .php_cs
file, which is
the local configuration that will be used instead of the project configuration. It
is a good practice to add that file into your .gitignore
file.
With the --config
option you can specify the path to the
.php_cs
file.
The example below will add two rules to the default list of PSR2 set rules:
<?php
$finder = PhpCsFixer\Finder::create()
->exclude('somedir')
->notPath('src/Symfony/Component/Translation/Tests/fixtures/resources.php')
->in(__DIR__)
;
return PhpCsFixer\Config::create()
->setRules([
'@PSR2' => true,
'strict_param' => true,
'array_syntax' => ['syntax' => 'short'],
])
->setFinder($finder)
;
NOTE: exclude
will work only for directories, so if you need to exclude file, try notPath
.
See Symfony\Finder online documentation for other Finder methods.
You may also use a blacklist for the rules instead of the above shown whitelist approach.
The following example shows how to use all Symfony
rules but the full_opening_tag
rule.
<?php
$finder = PhpCsFixer\Finder::create()
->exclude('somedir')
->in(__DIR__)
;
return PhpCsFixer\Config::create()
->setRules([
'@Symfony' => true,
'full_opening_tag' => false,
])
->setFinder($finder)
;
You may want to use non-linux whitespaces in your project. Then you need to configure them in your config file.
<?php
return PhpCsFixer\Config::create()
->setIndent("\t")
->setLineEnding("\r\n")
;
By using --using-cache
option with yes
or no
you can set if the caching
mechanism should be used.
The caching mechanism is enabled by default. This will speed up further runs by fixing only files that were modified since the last run. The tool will fix all files if the tool version has changed or the list of rules has changed. Cache is supported only for tool downloaded as phar file or installed via composer.
Cache can be disabled via --using-cache
option or config file:
<?php
return PhpCsFixer\Config::create()
->setUsingCache(false)
;
Cache file can be specified via --cache-file
option or config file:
<?php
return PhpCsFixer\Config::create()
->setCacheFile(__DIR__.'/.php_cs.cache')
;
Require friendsofphp/php-cs-fixer
as a dev
dependency:
$ ./composer.phar require --dev friendsofphp/php-cs-fixer
Then, add the following command to your CI:
$ CHANGED_FILES=$(git diff --name-only --diff-filter=ACMRTUXB "${COMMIT_RANGE}")
$ if ! echo "${CHANGED_FILES}" | grep -qE "^(\\.php_cs(\\.dist)?|composer\\.lock)$"; then IFS=$'\n' EXTRA_ARGS=('--path-mode=intersection' '--' ${CHANGED_FILES[@]}); fi
$ vendor/bin/php-cs-fixer fix --config=.php_cs.dist -v --dry-run --stop-on-violation --using-cache=no "${EXTRA_ARGS[@]}"
Where $COMMIT_RANGE
is your range of commits, eg $TRAVIS_COMMIT_RANGE
or HEAD~..HEAD
.
Exit code is built using following bit flags:
- 0 OK.
- 1 General error (or PHP minimal requirement not matched).
- 4 Some files have invalid syntax (only in dry-run mode).
- 8 Some files need fixing (only in dry-run mode).
- 16 Configuration error of the application.
- 32 Configuration error of a Fixer.
- 64 Exception raised within the application.
(applies to exit codes of the fix command only)
Dedicated plugins exist for:
The tool comes with quite a few built-in fixers, but everyone is more than welcome to contribute more of them.
A fixer is a class that tries to fix one CS issue (a Fixer
class must
implement FixerInterface
).
A config knows about the CS rules 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).
