Links Between Parameter And Argument
++++++++++++++++++++++++++++++++++++

  Collect various stats about arguments and parameter usage. 

A parameter is one slot in the method definition. An argument is a slot in the method call. Both are linked by the method and their respective position in the argument list.

+ Total number of argument usage, linked to a parameter : this excludes arguments from external libraries and native PHP functions. For reference.
+ Number of identical parameter : cases where argument and parameter have the same name. 
+ Number of different parameter : cases where argument and parameter have the different name. 
+ Number of expression argument : cases where argument is an expression
+ Number of constant argument : cases where the argument is a constant

.. code-block:: php
   
   <?php
   
   function foo($a, $b) {
       // some code
   }
   
   // $a is the same as the parameter
   // $c is different from the paramter $b
   foo($a, $c);
   
   const C = 1;
   
   // Foo is called with a constant (1rst argument)
   // Foo is called with a expression (2nd argument)
   foo(C, 1+3);
   
   ?>
