Real Variables
++++++++++++++

  Inventory of real variables. Global, `Static <https://www.php.net/manual/en/language.oop5.static.php>`_ and property declarations are skipped here. 
This is a refined version of a search on ``T_VARIABLE`` token.

.. code-block:: php
   
   <?php
   
   $realVariable = 1;
   
   class foo {
       private $property;        // not a variable
       
       private function bar() {
           global $global;       // not a variable
           static $static;       // not a variable
           
       }
   }
   
   ?>
