# Config based on PHP files

If you're using Symfony 5 and want to configure this bundle with a PHP file instead of a YAML,
you can set up the `config/packages/oneup_uploader.php` file like this:

```php

<?php declare(strict_types=1);

use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $configurator): void
{
    $configurator->extension('oneup_uploader', [
        'mappings' => [
            'gallery' => [
                'frontend' => 'dropzone'
            ]
        ]
    ]);
};

```
