Description:
------------
Hi,

while using a constant for defining a hyperlink-target (http-adress) and using this constand to do a header();redirect there comes an object not found-error (404) in the browser.

The reason is that php could not interpret the value of the constant and using the constants name for the header();-function.

Reproduce code:
---------------
Not working code:
<?php
	define('HOME', 'http://www.google.de');
	header("Location: HOME");
?>


WORKING CODE:
<?php
	define('HOME', 'http://www.google.de');
        $home_var = HOME;

	header("Location: $home_var");
?>

Expected result:
----------------
I expected a redirct to the defined value of the constant, in this example 'http://www.google.de'.

Actual result:
--------------
The browser is redircting to /HOME using the actual url of the page and just adding /HOME (which is the name of the constant, not the value) in the end of the adress bar.
