AS bonus");$stmt->bind_param('s', $eid);$stmt->execute();$stmt->bind_result($bonus);$stmt->fetch();?>printf("Your bonus is \$%01.2f",$bonus);Executing this example produces output similar to this:Your bonus is $295.02Retrieving Multiple RowsAlthough the above example should suffice for understanding how multiple rows are returned from astored routine, the following brief example makes it abundantly clear.
