Using the boolean param :

<?php

$first
= new ArrayIterator( array('k1' => 'a' , 'k2' => 'b''k3' => 'c''k4' => 'd') );
$second = new ArrayIterator( array( 'k1' => 'X', 'k2' => 'Y', 'Z' ) );

$combinedIterator= new AppendIterator();
$combinedIterator->append( $first );
$combinedIterator->append( $second );

var_dump( iterator_to_array($combinedIterator, false) );

?>

will output :

array(7) (
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
  [3]=>
  string(1) "d"
  [4]=>
  string(1) "X"
  [5]=>
  string(1) "Y"
  [6]=>
  string(1) "Z"
)

<?php

var_dump
( iterator_to_array($combinedIterator, true) );

?>

will output (since keys would merge) :

array(5) (
  ["k1"]=>
  string(1) "X"
  ["k2"]=>
  string(1) "Y"
  ["k3"]=>
  string(1) "c"
  ["k4"]=>
  string(1) "d"
  [0]=>
  string(1) "Z"
)

The use_keys parameter was added in one of the 5.2.x releases; it defaults to TRUE. This matches the behavior in PHP 5.1.6, which lacks this parameter.
