Description:
------------
It has come to my attention that trying to test if the number of rows returned by a prepared statement is somewhat broken. If we try $stmt->num_rows (alias of mysqli_stmt_num_rows obviously) we get 0 for results of both 0 and 1 rows.

Reproduce code:
---------------
Below is the code I used to reproduce this action. The structure is pretty much straight forward. The date field is of the MySQL DATE data type.


                if($stmt = $db->prepare("SELECT id, queries FROM ".STATS_TABLE." WHERE date = ? and id = ?"))
                {
                        $stmt->bind_param('si', $date, $this->id);
                        $stmt->execute();
                       
                        /* Get the results */
                        $stmt->bind_result($id, $query_count);
                        $stmt->fetch();
                        $stmt->store_result();
                       
                        /* $stmt->num_rows is an alias for mysqli_stmt_num_rows() */
                        echo($stmt->num_rows.'-'.$api_id);
                } 

Expected result:
----------------
A return of 0 on 0 row results and 1 on 1 row results

Actual result:
--------------
Return value of 0
