Php-cs-fixer: binary_operator_spaces breaks array keys containing UTF8 characters

Created on 3 Nov 2017 · 3Comments · Source: FriendsOfPHP/PHP-CS-Fixer

The PHP version you are using:

7.1.8

PHP CS Fixer version you are using:

2.7.1

The command you use to run the fixer (and the configuration file you are using if any).

vendor/bin/php-cs-fixer fix xxxx.php

// .php_cs

return PhpCsFixer\Config::create()
    ->setFinder($finder)
    ->setRules([
        'binary_operator_spaces' => [
            'operators' => [
                '=>'  => 'align_single_space_minimal',
            ],
        ],
    ]);

A minimal sample of valid PHP code that is not fixed correctly (if applicable).

before.php.txt

The fixed version of that code after you run the fixer and the version you expected.

after.php.txt

The fixer is incorrectly adding a space inside the third array key.
