  Core functions processing arrays.

These functions manipulate arrays in various ways. Arrays are essential for storing, managing, and operating on sets of variables.

This is not a real extension : it is a documentation section, that helps classifying the functions.

.. code-block:: php
   
   <?php
   function odd($var)
   {
       // returns whether the input integer is odd
       return($var & 1);
   }
   
   function even($var)
   {
       // returns whether the input integer is even
       return(!($var & 1));
   }
   
   $array1 = array('a'=>1, 'b'=>2, 'c'=>3, 'd'=>4, 'e'=>5);
   $array2 = array(6, 7, 8, 9, 10, 11, 12);
   
   echo 'Odd :'.PHP_EOL;
   print_r(array_filter($array1, 'odd'));
   echo 'Even:'.PHP_EOL;
   print_r(array_filter($array2, 'even'));
   ?>
