Fully Qualified Constants
+++++++++++++++++++++++++

  Constants defined with their namespace.

When defining constants with `define() <https://www.php.net/define>`_ function, it is possible to include the actual namespace : 
However, the name should be fully qualified without the initial \. Here, \a\b\c constant will never be accessible as a namespace constant, though it will be accessible via the `constant() <https://www.php.net/constant>`_ function.

Also, the namespace will be absolute, and not a relative namespace of the current one.

.. code-block:: php
   
   <?php
   
   define('a\b\c', 1); 
   
   ?>

Suggestions
___________

* Drop the initial \ when creating constants with define() : for example, use trim($x, '\'), which removes anti-slashes before and after.
