The pound # in $_SERVER variables

(1) test.php?test_key=test+value

$_SERVER['SCRIPT_NAME'] returns /test/test.php
$_SERVER['REQUEST_URI'] returns /test/test.php?test_key=test+value
$_SERVER['QUERY_STRING'] returns test_key=test+value

(2) test.php?test_key=test+value#test_internal_sublink

$_SERVER['SCRIPT_NAME'] returns /test/test.php
$_SERVER['REQUEST_URI'] returns /test/test.php?test_key=test+value
$_SERVER['QUERY_STRING'] returns test_key=test+value

Questions
(1) What do you call a sublink with the pound (#) symbol?
(2) How do I get to the #test_internal_sublink?
