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"
}
