iterator_to_array - Copy the iterator into an array

SYNOPSIS
       array iterator_to_array (Traversable  $iterator, [bool  $use_keys = true])

DESCRIPTION
	Copy the elements of an iterator into an array.

PARAMETERS
	      o $iterator
		- The iterator being copied.

	      o $use_keys
		- Whether to use the iterator element keys as index.  In PHP 5.5 and later, if a key is an array or object, a warning will be gen-
		erated.  NULL keys will be converted to an empty string, double keys will be truncated to their integer counterpart, resource keys
		will generate a warning and be converted to their resource ID, and boolean keys will be converted to integers.

RETURN VALUES
	An array containing the elements of the $iterator.

EXAMPLES
       Example #1

	      iterator_to_array(3) example

	      <?php
	      $iterator = new ArrayIterator(array('recipe'=>'pancakes', 'egg', 'milk', 'flour'));
	      var_dump(iterator_to_array($iterator, true));
	      var_dump(iterator_to_array($iterator, false));
	      ?>

	      The above example will output:

	      array(4) {
		["recipe"]=>
		string(8) "pancakes"
		[0]=>
		string(3) "egg"
		[1]=>
		string(4) "milk"
		[2]=>
		string(5) "flour"
	      }
	      array(4) {
		[0]=>
		string(8) "pancakes"
		[1]=>
		string(3) "egg"
		[2]=>
		string(4) "milk"
		[3]=>
		string(5) "flour"
