Symfony - Serve Private File

Following example demonstrates how to:

display a private file download prompt to the user (here for a PDF file)
serve a private image or PDF which will be displayed on a webpage

See https://symfony.com/doc/4.4/components/http_foundation.html#serving-files

Host these files in a directory outside of /public, so they can be accessed only through the controller and its @Security() authorization. For example you could create a /private-uploads directory at the root of your project.

Law of Demeter with PHP (LoD)

Law of Demeter or principle of least knowledge is a design guideline, that is using to make code more simple and stable.

Rules for module

Each unit should have only limited knowledge about other units: only units "closely" related to the current unit.
Each unit should only talk to his friends; don't talk to strangers.
Only talk to your immediate friends.

Update - 4 september 2020

Making multiple MySQL versions work with Homebrew was tricky to say the least. Fortunately there are 2 new easy ways that I learned of to achieve this.

DBngin app

As @4unkur and @henrytirla commented below, there is this extremely easy to use app called DBngin, which lets you setup multiple databases (not only MySQL) simultaneously using different ports:

	use Rector\CodeQuality\Rector\Class_\CompleteDynamicPropertiesRector;
	use Rector\Config\RectorConfig;

	return static function (RectorConfig $rectorConfig): void {
	$rectorConfig->rule(CompleteDynamicPropertiesRector::class);

	// Define directories to check
	$directories = [

	// php identify.php http://magento2demo.firebearstudio.com/pub/static/frontend/Magento/luma/en_US/requirejs-config.js

	$content = file_get_contents($argv[1]);
	preg_match_all(
	'/(?P<quote>\'\|")(?P<extension>[[:alnum:]]+_[[:alnum:]]+)\/js\/.+?(?P=quote)/m',
	$content,
	$matches
