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" }
