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

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

To get the base URL you can use this  would return  http    localhost yiistore2 upload    Yii  app  - gt baseUrl   The following Code would return just  localhost yiistore2 upload  without http s      Yii  app  - gt getBaseUrl true    Or you could get the webroot path   would return  d  wamp www yii2store    Yii  getPathOfAlias  webroot

Supposing you have a writable  uploads  folder in your application   You can define a param like this   Yii   app- gt params  uploadPath     realpath Yii   app- gt basePath      uploads      Then you can simply use the parameter as    path1   Yii   app- gt params  uploadPath      filename    Just depending on if you are using advanced or simple template the base path will be  following the link provided by phazei       Simple  app  Your application root directory      Advanced  app  Your application root directory  either frontend or   backend or console depending on where you access it from    This way the application will be more portable than using realpath dirname   FILE
