Elenco dei parametri

NULL keys will be converted to an empty string, double keys will be truncated to their integer counterpart, resource keys will generate a warning and be converted to their resource ID, and boolean keys will be converted to integers.

Valori restituiti

An array containing the elements of the iterator.
