Useless Try
+++++++++++

  Report try clause that are useless. A try clause is useless when no `exception <https://www.php.net/exception>`_ is emitted by the code in the block. 



This happens when the underlying layers removed the emission of exceptions.

.. code-block:: php
   
   <?php
   
   try {
   	// Nothing is going to happen here
   	++$a;
   } catch (Exception $e) {
   
   }
   
   ?>

Suggestions
___________

* Remove the Try clause
* Add a throw among the different called methods
