How to get CiviCRM root via PHP?

Question

I'm working on an extension and I need to include a PHP file that is in the civicrm module root dir. Is there a way to get this directory through PHP? I need it to work for all CMS, not just Drupal.

Thanks!

I found the answer in the docs here: https://docs.civicrm.org/dev/en/latest/framework/filesystem/#tip-programmatic-lookup_1

You can use the following:

Civi::paths()->getPath("[civicrm.root]/.")

or

global $civicrm_root;
