Answer 1

If you want to get the root directory of your yii2 project use, assuming that the name of your project is project_app you'll need to use:

echo Yii::getAlias('@app');

on windows you'd see "C:\dir\to\project_app"

on linux you'll get "/var/www/dir/to/your/project_app"

I was formally using:

echo Yii::getAlias('@webroot').'/..';

I hope this helps someone
