Already Parents Trait
+++++++++++++++++++++

  Trait is already used a `parent <https://www.php.net/manual/en/language.oop5.paamayim-nekudotayim.php>`_'s class or trait. There is no use to include it a second time, so one of them can be removed.

.. code-block:: php
   
   <?php
   
   trait ta {
       use tb;
   }
   
   trait t1 {
       use ta;
       use tb; // also used by ta
   }
   
   class b {
       use t1; // also required by class c
       use ta; // also required by trait t1
   }
   
   class c extends b {
       use t1;
   }
   
   ?>
