Intervention/image

The app function returns the service container instance:

$container = app();

        $mime = finfo_buffer(finfo_open(FILEINFO_MIME_TYPE), $data);

        $length = strlen($data);

        if (function_exists('app') && is_a($app = app(), 'Illuminate\Foundation\Application')) {

            $response = IlluminateResponse::make($data);

            $response->header('Content-Type', $mime);
