数据库数据调用问题
表 business_circle
字段 id  name  parent_id 
       1   朝阳     0
       2   昌平     0
       3   大望路   1
       4   呼家楼   1
       5   朝阳公园 1

$sql1 = mysql_query("select * from business_circle order by id asc");
while($rs1 = mysql_fetch_assoc($sql1)){
echo $rs1['name'].$rs1['parent_id'].'
';
}
调出的结果是
大望路   1
呼家楼   1
朝阳公园 1

parent_id就是父类的id
我想调出的结果是
大望路 朝阳
呼家楼 朝阳
朝阳公园 朝阳
