# PHP Coding Standards Fixer
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 (team's) 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.
## Supported PHP Versions
* PHP 7.4
* PHP 8.0
* PHP 8.1
* PHP 8.2
* PHP 8.3
> **Note**
> Each new PHP version requires a huge effort to support the new syntax.
> That's why the latest PHP version might not be supported yet. If you need it,
> please, consider supporting the project in any convenient way, for example
> with code contribution or reviewing existing PRs. To run PHP CS Fixer on yet
> unsupported versions "at your own risk" - leverage the
> [PHP_CS_FIXER_IGNORE_ENV](./doc/usage.rst#environment-options).
## Documentation
### Installation
The recommended way to install PHP CS Fixer is to use [Composer](https://getcomposer.org/download/)
in a dedicated `composer.json` file in your project, for example in the
`tools/php-cs-fixer` directory:
```console
mkdir -p tools/php-cs-fixer
composer require --working-dir=tools/php-cs-fixer friendsofphp/php-cs-fixer
```
Or using the main `composer.json`:
```console
composer require --dev friendsofphp/php-cs-fixer
```
For more details and other installation methods, see
[installation instructions](./doc/installation.rst).
### Run with Docker
You can use pre-built Docker images to run ``php-cs-fixer``.
```console
docker run -it --rm -v $(pwd):/code ghcr.io/php-cs-fixer/php-cs-fixer:${FIXER_VERSION:-3-php8.3} fix src
```
`$FIXER_VERSION` used in example above is an identifier of a release you want to use, which is based on Fixer and PHP versions combined. There are different tags for each Fixer's SemVer level and PHP version with syntax `-php`. For example:
* `3.57.0-php7.4`
* `3.57-php8.0`
* `3-php8.3`
### Usage
Assuming you installed PHP CS Fixer as instructed above, you can run the
following command to fix the PHP files in the `src` directory:
```console
tools/php-cs-fixer/vendor/bin/php-cs-fixer fix src
```
See [usage](./doc/usage.rst), list of [built-in rules](./doc/rules/index.rst), list of [rule sets](./doc/ruleSets/index.rst)
and [configuration file](./doc/config.rst) documentation for more details.
If you need to apply code styles that are not supported by the tool, you can
[create custom rules](./doc/custom_rules.rst).
