How to get the root dir of the Symfony2 application

Question

What is the best way to get the root app directory from inside the controller  Is it possible to get it outside of the controller   Now I get it by passing it  from parameters  to the service as an argument  like this   services       sr processor          class  Pro Processor         arguments    kernel root dir     Is there a better  simpler way to get this information in Symfony2

UPDATE 2018-10-21   As of this week  getRootDir   was deprecated  Please use getProjectDir   instead  as suggested in the comment section by Muzaraf Ali      -  Use this     this- gt get  kernel  - gt getRootDir      And if you want the web root    this- gt get  kernel  - gt getRootDir          web     this- gt getRequest  - gt getBasePath      this will work from controller action method     EDIT  As for the services  I think the way you did it is as clean as possible  although I would pass complete kernel service as an argument    but this will also do the trick

If you are using this path to access parts of the projects which are not code  for example an upload directory  or a SQLite database  then it might be better to turn the path into a parameter  like this   parameters      database path    kernel root dir     var sqlite3 db    This parameter can be injected everywhere you need it  so you don t have to mess around with paths in your code any more  Also  the parameter can be overridden at deployment time  Finally  every maintaining programmer will have a better idea what you are using it for   Update  Fixed kernel root dir constant usage

Since Symfony 3 3 you can use binding  like  services   defaults      autowire  true           autoconfigure  true     bind           kernelProjectDir    kernel project dir     After that you can use parameter  kernelProjectDir in any controller OR service  Just like  class SomeControllerOrService       public function someAction        kernelProjectDir
