How to get root directory in yii2

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.

Answer

Open file D:\wamp\www\yiistore2\common\config\params-local.php

Paste below code before return

Yii::setAlias('@anyname', realpath(dirname(__FILE__).'/../../'));

After inserting above code in params-local.php file your file should look like this.

Yii::setAlias('@anyname', realpath(dirname(__FILE__).'/../../'));

return [
];

Now to get path of your root (in my case its D:\wamp\www\yiistore2) directory you can use below code in any php file.

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