Continue Is For Loop
++++++++++++++++++++

  `break <https://www.php.net/manual/en/control-structures.break.php>`_ and `continue <https://www.php.net/manual/en/control-structures.continue.php>`_ are very similar in PHP : they both `break <https://www.php.net/manual/en/control-structures.break.php>`_ out of loop or switch. Yet, `continue <https://www.php.net/manual/en/control-structures.continue.php>`_ should be reserved for loops.

Since PHP 7.3, the execution emits a warning when finding a ``continue`` inside a ``switch`` : '"`continue <https://www.php.net/manual/en/control-structures.continue.php>`_" targeting switch is equivalent to "`break <https://www.php.net/manual/en/control-structures.break.php>`_". Did you mean to use "`continue <https://www.php.net/manual/en/control-structures.continue.php>`_ 2"?'

.. code-block:: php
   
   <?php
   
   while ($foo) {
       switch ($bar) {
           case 'baz':
               continue; // In PHP: Behaves like 'break;'
                         // In C:   Behaves like 'continue 2;'
       }
   }
   
   ?>
