Wrong Class Name Case
+++++++++++++++++++++

  The spotted classes are used with a different case than their definition. While PHP accepts this, it makes the code harder to read. 

It may also be a violation of coding conventions.

.. code-block:: php
   
   <?php
   
   // This use statement has wrong case for origin.
   use Foo as X;
   
   // Definition of the class
   class foo {}
   
   // Those instantiations have wrong case
   new FOO();
   new X();
   
   ?>
