How to get root directory in yii2

Question

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');
