Description
___________
 
It is not possible to use attributes on global constants, when several constants are defined at the same time. That syntax is possible with class constants, but not with global constants.

Example
_______

.. code-block:: php

   <?php
   
   #[Foo]
   const A = 1,
         B = 2;
   
   ?>

Solutions
_________

+ Split the constant definitions, and apply the same attribute to each of them.
+ Convert the global constants to class constants.
