A Customised fixer for PHP-CS-Fixer to use `prettier`'s php plugin to pre-process the code before getting analysed by other fixers. This would enable `php-cs-fixer` to take advantage of `prettier`'s ability of managing long line.

.php_cs.dist

<?php

require_once __DIR__.'/relative/path/to/PrettierPHPFixer/File';

        (new PrettierPHPFixer()),
    ])

        'Prettier/php' => true,
    ]);

Prettier integration to php-cs-fixer

This recipe uses prettier/plugin-php as a Fixer for php-cs-fixer.

prettier will be executed at the very beginning before the other fixers are
applied, such that the php-cs-fixer user's configurations is respected.

Useful Configurations

Priority

If you would like prettier to execute last, which means you prefer to use
php-cs-fixer to complement the current missing features of prettier, you
can decrease the priority value of this fixer by decreasing the value returned
by getPriority function to something like -999

Prettier's native configuration

If you would like to add configuration settings for prettier to this Fixer,
you can modify the exec line in applyFix function.

For example,

  - exec("yarn exec -- prettier --write --brace-style=1tbs $tmpFile");
  + exec("yarn exec -- prettier --write --brace-style=psr-2 $tmpFile");

will allow you to change the braceSytle for this fixer

Possible Improvement

• the configuration can be modified from php-cs-fixer configuration
• autoloading

Thanks for this. I had to make few changes to make it work. For those having some problems can look at my fork - https://gist.github.com/piyush1104/5eba790d07834b2efbb5ac7e690e6555. It might work for you then.

Thank you for your interest, also if you have any improvement that will make it work better, feel free to create a pull request for prettier directly as this recipe is included in prettier repo at https://github.com/prettier/plugin-php/blob/master/docs/recipes/php-cs-fixer/, cheers.

Sorry, I already saw that my comments were already incorporated in the repo you are mentioning. I deleted my comments just before you posted your reply. 😄

Hi I want to apply your gist to the prettier plugin for PHPStorm. How can i do this? I can not find the two files you mention above
