the directory for cakephp in xml generation

I uploaded xml file in my cakephp in img/files directory

app->webroot->files->Myfile.xml

and I want to call it from my controller like 开发者_Python百科this

$file = "/files/Myfile.xml";

I am not sure is this the correct path from the controller ot not of course controller is in app->controllers->my_controller

thanks

Use one of the CakePHP Core Configuration Constants.

WWW_ROOT for example:

$file = WWW_ROOT . "files/MyFiles.xml";
