How to get root directory in yii2

Question

yii2 Question

My yii2 install in d:\wamp\www\yii2store

I want to get above path to save images which will be uploaded by me or users.

I have pass all available arguments in Yii::getAlias('@webroot') (below are the lists of argument which I have used).

@yii - framework directory.

@app - base path of currently running application.

@runtime - runtime directory.

@vendor - Composer vendor directory.

@webroot - web root directory of currently running web application.

@web - base URL of currently running web application.

And also once I will get above path to save images then how can I get path something like this localhost/yiistore2/upload to be use in img tag src.

One more thing how can I create my own alias with Yii::setAlias() and where to create this so that I can load it on every controller.

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
