request_path()

Returns the requested URL path of the page being viewed.

Examples:

• http://example.com/node/306 returns "node/306".
• http://example.com/drupalfolder/node/306 returns "node/306" while 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.

    // This is a request with a ?q=foo/bar query string. $_GET['q'] is
    // overwritten in drupal_path_initialize(), but request_path() is called
    // very early in the bootstrap process, so the original value is saved in
    // $path and returned in later calls.
