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.
