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
