Mini Project with Composer

1. step: create composer.json

{
    "autoload": {
        "psr-4": {
            "MayApp\\": "src/MyApp"
        },
        "classmap": [
            "src/MyApp"
        ]
    },
    "require-dev": {
        "phpunit/phpunit": "^7.3",
        "friendsofphp/php-cs-fixer": "^2.12"
    },
    "scripts": {
        "test": "vendor/bin/phpunit tests/",
        "fix": "vendor/bin/php-cs-fixer fix"
    }
}

2. step: create .php_cs

<?php

$finder = PhpCsFixer\Finder::create()
    ->exclude([
        'vendor',
    ])
    ->in(__DIR__)
;

return PhpCsFixer\Config::create()
    ->setRules([
        '@Symfony' => true,
        'yoda_style' => [
            'equal' => null,
            'identical' => null,
            'less_and_greater' => null,
        ],
        'concat_space' => ['spacing' => 'one'],
        'declare_equal_normalize' => ['space' => 'single'],
        'array_syntax' => ['syntax' => 'short'],
        'phpdoc_align' => [
            'align' => 'left',
            'tags' => ['param', 'property', 'return', 'throws', 'type', 'var', 'method']
        ],
        'phpdoc_to_comment' => false,
        'no_superfluous_phpdoc_tags' => true,
    ])
    ->setFinder($finder)
;

3. step: create all folders

mkdir -p src/MyApp tests

4. step: composer install and start

composer test
composer fix
