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.


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


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

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=all

By default, all PSR-2 fixers and some additional ones are run.

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

Choose from the list of available fixers:

  • indentation [PSR-2] Code must use 4 spaces for indenting, not tabs.

  • linefeed [PSR-2] All PHP files must use the Unix LF (linefeed) line ending.

  • trailing_spaces [PSR-2] Remove trailing whitespace at the end of lines.

  • phpdoc_params [all] All items of the @param phpdoc tags must be aligned vertically.

  • unused_use [all] Unused use statements must be removed.

  • short_tag [PSR-1] PHP code must use the long tags or the short-echo tags; it must not use the other tag variations.

  • return [all] An empty line feed should precede a return statement.

  • extra_empty_lines [all] Removes extra empty lines.

  • eof_ending [all] A file must always ends with an empty line feed.

  • visibility [PSR-2] Visibility must be declared on all properties and methods; abstract and final must be declared before the visibility; static must be declared after the visibility.

  • braces [PSR-2] Opening braces for classes and methods must go on the next line, and closing braces must go on the next line after the body. Opening braces for control structures must go on the same line, and closing braces must go on the next line after the body.

  • php_closing_tag [PSR-2] The closing ?> tag MUST be omitted from files containing only PHP.

  • controls_spaces [all] A single space should be between: the closing brace and the control, the control and the opening parenthese, the closing parenthese and the opening brace.

  • elseif [PSR-2] The keyword elseif should be used instead of else if so that all control keywords looks like single words.

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

# For the Symfony 2.1 branch
php php-cs-fixer.phar fix /path/to/sf21 --config=sf21

Choose from the list of available configurations:

  • default A default configuration

  • magento The configuration for a Magento application

  • sf20 The configuration for the Symfony 2.0 branch

  • sf21 The configuration for the Symfony 2.1 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 and the files and directories that need to be analyzed:


$finder = Symfony\CS\Finder\DefaultFinder::create()

return Symfony\CS\Config\Config::create()
    ->fixers(array('indentation', 'elseif'))


Dedicated plugins exist for:


The tool comes with quite a few built-in fixers and finders, 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 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).
