How can I retrieve the path to the root directory in WordPress CMS?

You can use get_site_url() function to get the base url of the wordpress site. Show activity on this post. First of all, this returns the path to the current template, and second, it returns the URI, not the filesystem path.
In order to get the root directory path, you can use _DIR_ or dirname(). echo dirname(__FILE__); Both the above syntaxes will return the same result.
Looking at the bottom of your wp-config.php file in the wordpress root directory will let you find something like this:
if ( !defined('ABSPATH') ) define('ABSPATH', dirname(__FILE__) . '/'); For an example file have a look here:
http://core.trac.wordpress.org/browser/trunk/wp-config-sample.php
You can make use of this constant called ABSPATH in other places of your wordpress scripts and in most cases it should point to your wordpress root directory.
