<caution>
<para>
При использовании функции <function>iterator_to_array</function> для копирования значения AppendIterator
в массив, вам необходимо установить дополнительный аргумент <parameter>use_key</parameter> в значение
&false;. Когда <parameter>use_key</parameter> не принимает значение &false;, какие-либо ключи, повторно встречающиеся во внутренних
итераторах, будут перезаписаны в возвращаемый массив. Сохранить оригинальные ключи невозможно.
