EXAMPLES

       Example #1

	      array_chunk(3) example

	      <?php
	      $input_array = array('a', 'b', 'c', 'd', 'e');
	      print_r(array_chunk($input_array, 2));
	      print_r(array_chunk($input_array, 2, true));
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => Array
		      (
			  [0] => a
			  [1] => b
		      )

		  [1] => Array
		      (
			  [0] => c
			  [1] => d
		      )

		  [2] => Array
