Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php

define() does no checking of the name.

Description:
------------
Defining a namespace who's name starts with a \ is interpreted as a
constant though resolving a constant for the namespace name is not
supported (and should not! :) ) and results in an empty string being
used.


Test script:
---------------
test.php:

<?php
 define('a','\foo');
 require 'a.php';


a.php:

<?php
namespace \a; 
var_dump(__NAMESPACE__);
class b { }

Expected result:
----------------
(Parse?) Error due to invalid namespace definition

Actual result:
--------------
Empty string for __NAMESPACE__ or undefined constant a depending wheter
or not the file "a.php" got required or called directly
