the difference of this method and the direct assign the object to a value is as follows:

result:
object(ArrayIterator)#1 (1) { ["storage":"ArrayIterator":private]=> array(4) { ["name"]=> string(7) "mengzhi" ["age"]=> string(2) "12" ["city"]=> string(8) "shanghai" [0]=> array(2) { ["home"]=> string(5) "china" ["work"]=> string(9) "developer" } } } 
array(4) { ["name"]=> string(7) "mengzhi" ["age"]=> string(2) "12" ["city"]=> string(8) "shanghai" [0]=> array(2) { ["home"]=> string(5) "china" ["work"]=> string(9) "developer" } }

Just in case some of you out there do NOT know this: 
(a). 'getArrayCopy()', returns a copy of the ORIGINAL array - iterator object. Therefore, using (for example) 'LimitIterator' on an array-object, and then calling 'getArrayCopy' afterwards, might not return the current (adjusted) object. 
(b). Instead, use the 'iterator_to_array' function, in order to access, or return, the current state of the array-object-iterator (whatever). Using the example above (in '(a)'); passing the 'LimitIterator' object into 'iterator_to_array', should return the CURRENT, and NOT ORIGINAL state of your array (iterator object).
