The <function>mysqli_stmt_data_seek</function> function seeks to an arbitrary result pointer
specified by the <parameter>offset</parameter> in the statement result set represented by
<parameter>statement</parameter>. The <parameter>offset</parameter> parameter must be between
zero and the total number of rows minus one (0..<function>mysqli_stmt_num_rows</function> - 1).
