Could Use Namespace Magic Constant
++++++++++++++++++++++++++++++++++

  Use the `__NAMESPACE__ <https://www.php.net/manual/en/language.constants.predefined.php>`_ magic constant, instead of hardcoding the current namespace. That way, the namespace is easier to read, and it will change with the namespace expression.

.. code-block:: php
   
   <?php
   
   namespace A\B\C {
   	class D {}
   	$className = 'D';
   
   	// hardcoded namespace, needed to instantiate dynamically the class
   	// Don't forget the extra \ 
   print	$fullclassName = '\'.__NAMESPACE__.'\'.$className;
   	$object = new $fullclassName;
   	
   	
   	// hardcoded namespace, needed to instantiate dynamically the class
   	$path = "\A\B\C"; 
   	$fullclassName = $path.$className;
   	$object = new $fullclassName;
   
   }
   ?>
