Identical Case In Switch
++++++++++++++++++++++++

  In a `switch() <https://www.php.net/manual/en/control-structures.switch.php>`_ or `match() <https://www.php.net/manual/en/control-structures.match.php>`_ statement, when there are identical cases, it means that multiple case labels that have the same code block. 

This can happen by mistake or design. They may be merged together.

.. code-block:: php
   
   <?php
   
   switch($a) {
   	case 1: 
   		$b = 2;
   		break;
   
   	case 2: 
   		$b = 12;
   		break;
   
   	// Identical to case 1
   	case 3: 
   		$b = 2;
   		break;
   }
   
   ?>
