iterator_to_array

(PHP 5 >= 5.1.0, PHP 7)
Copy the iterator into an array
array iterator_to_array ( Traversable $iterator [, bool $use_keys = true ] )

Copy the elements of an iterator into an array.

Parameters:
iterator

The iterator being copied.

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 generated. 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.

Returns:

An array containing the elements of the iterator.

Changelog:
5.5.0

iterator_to_array() integer string use_keys

5.2.1

The use_keys parameter was added.

Examples:
iterator_to_array() 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"
}
