A very important thing to note about \RecursiveIteratorIterator is that it returns a flattened array when used with the iterator_to_array function. Ex:

<?php
$arr
= array('Zero', 'name'=>'Adil', 'address' => array( 'city'=>'Dubai', 'tel' => array('int' => 971, 'tel'=>12345487)), '' => 'nothing');

$iterator = new \RecursiveIteratorIterator(new \RecursiveArrayIterator($arr));
var_dump(iterator_to_array($iterator,true));
?>

This code will return :

array(6) {
[0]=>
string(4) "Zero"
["name"]=>
string(4) "Adil"
["city"]=>
string(5) "Dubai"
["int"]=>
int(91)
["tel"]=>
int(12345487)
[""]=>
string(7) "nothing"
}

To get the non-flattened proper array use the getArrayCopy() method, like so :

$iterator->getArrayCopy()

This will return

array(4) {
[0]=>
string(4) "Zero"
["name"]=>
string(4) "Adil"
["address"]=>
array(2) {
["city"]=>
string(5) "Dubai"
["tel"]=>
array(2) {
["int"]=>
int(91)
["tel"]=>
int(12345487)
}
}
[""]=>
string(7) "nothing"
}
