Here are the most commonly used path variables in drupal

$base_root
$base_url
$base_path

Suppose our site is hosted at http://www.example.com/examplesite

The $base_root would give the URL of the host, excluding the path.
$base_root would return http://www.example.com

The $base_url does not include the trailing slash.
$base_url would return http://www.example.com/examplesite

The $base_path would give the base url of the drupal installation
$base_path would return /examplesite/
