Then, use the phpinsights binary:

php ./vendor/bin/phpinsights

Within Laravel

First, you should publish the config-file with:

php artisan vendor:publish --provider="NunoMaduro\PhpInsights\Application\Adapters\Laravel\InsightsServiceProvider"

Then, use the insights Artisan command:

php artisan insights

Within Symfony

First, you should create the config-file with:

cp vendor/nunomaduro/phpinsights/stubs/symfony.php phpinsights.php

Then, use the phpinsights binary:

php ./vendor/bin/phpinsights

No framework - customize `Insights`

You may customize insights creating and editing the configuration file:

cp vendor/nunomaduro/phpinsights/stubs/config.php phpinsights.php

PHP Insights console command have different verbosity levels, which determine the quantity of issues displayed. By default, commands display only the 3 first issues per Insight, but you can display them all with the -v option:

php ./vendor/bin/phpinsights -v

The project is under development. As such, any help is welcome!

Create a new insight from scratch
Add a new insight from PHP CS Sniff
Create or improve create a preset for your favorite framework
Create the test suite

Create a new `Insight`

Imagine that you want to create a new Insight that doesn't allow the usage of final classes:

Create a new file under src/Domain/Insights with the content:

final class ForbiddenFinalClasses extends Insight
{
    public function hasIssue(): bool
    {
        return (bool) count($this->collector->getConcreteFinalClasses());
    }

    public function getTitle(): string
    {
        return 'The use of `final` classes is prohibited';
    }
}

Attach the Insight to a specific inside src/Domain/Metrics:

final class Classes implements HasInsights
{
    // ...

    public function getInsights(): array
    {
        return [
            ForbiddenFinalClasses::class,
        ];
    }
}

Add a new insight from PHP CS Sniff

Are you aware of a PHPCS sniff that you would like to add to PHP Insights? You can add it in the following way:

Identify the related metric, and add it to the list of insights:

final class Classes implements HasInsights
{
    // ...

    public function getInsights(): array
    {
        return [
            UnusedPropertySniff::class,
        ];
    }
}

Create or improve create a preset for your favorite framework

Would you like to exclude a directory or remove an Insight for your favorite framework? You can add it in the following way:

In this example we are going to use the Laravel Framework.

Open the file src/Application/Adapters/Laravel/Preset.php and update the config file:

final class Preset implements PresetContract
{
    public static function getName(): string
    {
        return 'laravel';
    }

    public static function get(): array
    {
        return [
            'exclude' => [
                'config',
                'storage',

                '_ide_helper_models.php',
                'public',
            ],
            'add' => [
                Classes::class => [
                    ForbiddenFinalClasses::class,
                ],
            ],

            'remove' => [
                AlphabeticallySortedUsesSniff::class,
                DeclareStrictTypesSniff::class,
                DisallowMixedTypeHintSniff::class,
                ForbiddenDefineFunctions::class,
                ForbiddenNormalClasses::class,
                ForbiddenTraits::class,
                TypeHintDeclarationSniff::class,
            ],

            'config' => [
                ForbiddenPrivateMethods::class => [
                    'title' => 'The usage of private methods is not idiomatic in Laravel.',
                ],
                ForbiddenDefineGlobalConstants::class => [
                    'ignore' => ['LARAVEL_START'],
                ],
                ForbiddenFunctionsSniff::class => [
                    'forbiddenFunctions' => [
                        'dd' => null,
                        'dump' => null,
                    ],
                ],
            ],
        ];
    }
