Redeclared PHP Functions
++++++++++++++++++++++++

  Function that bear the same name as a PHP function, and that are declared. 

This is useful when managing backward compatibility, like emulating an old function, or preparing for newer PHP versions, like emulating new upcoming function.

.. code-block:: php
   
   <?php
   
   if (version_compare(PHP_VERSION, 7.0) > 0) {
       function split($separator, $string) {
           return explode($separator, $string);
       }
   }
   
   print_r( split(' ', '2 3'));
   
   ?>
