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.
The recommended way to install PHP CS Fixer is to use Composer
in a dedicated
composer.json file in your project, for example in the
$ mkdir --parents tools/php-cs-fixer $ composer require --working-dir=tools/php-cs-fixer friendsofphp/php-cs-fixer
For more details and other installation methods, see installation instructions.
Assuming you installed PHP CS Fixer as instructed above, you can run the
following command to fix the files PHP files in the
$ tools/php-cs-fixer/vendor/bin/php-cs-fixer fix src
If you need to apply code styles that are not supported by the tool, you can create custom rules.
