You can assign aliases to columns in your SELECT
clause to give them distinct names in your result.
E.g.
SELECT hotel.HNo, hotel.Name AS hotelName, hotel.Description AS hotelDesc, hotel.Location AS hotelLocation
and then you refer to these aliases when working with the rows contained in your query result. E.g.
while($data = mysql_fetch_array($sql)) {
echo $data['hotelName'];
...
}
