Which one of the following method is used to retrieve the number of rows affected by an INSERT, UPDATE, or DELETE query? Correct Answer mysqli_affected_rows()
The method mysqli_num_rows() is only useful for determining the number of rows retrieved by a SELECT query. But to retrieve the number of rows affected by INSERT, UPDATE, or DELETE query, use mysqli_affected_rows(). Num_rows() and affected_rows() were used in previous version of PHP.
