Wrong Function Name Case
++++++++++++++++++++++++

  The spotted functions 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
   
   // Definition of the class
   function foo () {}
   
   // Those calls have wrong case
   FOO();
   \Foo();
   
   // This is valid
   foo();
   
   ?>

Suggestions
