What is the correct way to obtain the Drupal installed document root?

Inside of a Drupal module I need to obtain the base path where the Drupal site is installed.

For example, if the drupal site is installed at: www.example.com/mysite/ then I want to get '/var/www/myseite'

If it is installed in: www.example.com/ then I want '/var/www'

What is the proper Drupal way to get this? I want to avoid PHP's server variables, as I read they are unreliable.

(Drupal 6 and Drupal 7)

Solution

  • In Drupal 7, there is a new constant called DRUPAL_ROOT which you can use for this.
