Best way to find the system and application folders above the web root in CI3?

OK, so for the project I'm working on right now, I've decided to make it find the system and application folders like this:

PHP Code:

$system_path = __DIR__.DIRECTORY_SEPARATOR.\'../system';
$application_folder = __DIR__.DIRECTORY_SEPARATOR.\'../application'; 


and it seems to work for me. Is that what you meant, ciadmin?

Yup. Better separation of concerns, even if a .htaccess file could prevent access to them

Great! I'm glad that something about this topic exists on the internet now. Thank you.
Is there anywhere I could post about the project I used this in?
