예약스킨을 커스터마이징하고 있는 중인데 db 추출해오는 문제를 잘 모르겠네요..

<code>

// 객실정보
unset($arr_room);
$arr_room = array();
$query = "select * from {$g5['wzp_room_table']} order by rm_sort asc ";
$res = sql_query($query);
while($row = sql_fetch_array($res)) {
    $row['price'] = wz_calculate($row['rm_ix'], $today_type);   
    $arr_room[] = $row;
}
$cnt_room = count($arr_room);
sql_free_result($res);

룸 테이블에 있는 정보 중에 size에 대해 1,2,3으로 나누어진 데이터를 추출해내려고 합니다

이런식으로 if나 switch문을 사용하여 방 크기(size)가 1또는 2또는 3 등등이 될 때 거기에 해당하는

데이터만 뽑아내려고하는데 소스를 어디에 어떻게 추가하면 될까요??
