- * Returns the requested URL path of the page being viewed.

- * - http://example.com/node/306 returns "node/306".

- *   base_path() returns "/drupalfolder/".
- * - http://example.com/path/alias (which is a path alias for node/306) returns
- *   "path/alias" as opposed to the internal path.
- * - http://example.com/index.php returns an empty string (meaning: front page).
- * - http://example.com/index.php?page=1 returns an empty string.
