Variables With Long Names
+++++++++++++++++++++++++

  This analysis collects all variables with more than 20 characters longs. This may be configured with the ``variableLength`` parameter.
PHP has not limitation on variable name size. While short name are often obscure, long names are usually better. Yet, there exists a limit to convenient variable name length.

.. code-block:: php
   
   <?php
   
   // Quite a long variable name
   $There_is nothing_wrong_with_long_variable_names_They_tend_to_be_rare_and_that_make_them_noteworthy = 1;
   
   ?>
