Setting PHP constants as parameters is also supported.
To take advantage of this feature, map the name of your constant to a parameter
key and define the type as ``constant``.

.. configuration-block::

.. code-block:: yaml

parameters:
global.constant.value: !php/const:GLOBAL_CONSTANT
my_class.constant.value: !php/const:My_Class::CONSTANT_NAME

.. code-block:: xml
