- NestedArray::mergeDeepArray(array($a, $b));
The following are also equivalent:
- call_user_func_array('NestedArray::mergeDeep', $arrays_to_merge);
- NestedArray::mergeDeepArray($arrays_to_merge);
Parameters

bool $preserve_integer_keys: (optional) If given, integer keys will be preserved and merged instead of appended. Defaults to FALSE.
Return value
