array iterator_to_array ( Traversable $iterator [, bool $use_keys = true ] )Copy the elements of an iterator into an array.
Parameters

The iterator being copied.

In PHP 5.5 and later, if a key is an array or object, a warning will be generated. 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.
Note: If this parameter is not set or set to
TRUE, duplicate keys will be overwritten. The last value with a given key will be in the returned array. Set this paramater toFALSEto get all the values in any case.
Return Values
An array containing the elements of the iterator.
