HomeBackend DevelopmentPHP Tutorial根据访客来源显示不同的新闻

用的是淘宝IP库
$ipinfo=json_decode(file_get_contents("http://ip.taobao.com/service/getIpInfo.php?ip=".$onlineip),true);
现在可以成功知道访客来源了。
我想的问的是,类似于腾讯首页那样,根据访客来源显示所在省的新闻。
接下来该怎么写。求完成的。

比如:用淘宝IP库:
echo '省份:'.$ipinfo['data']['region'];
数据库A,数据表B,数据表B有字段tiele,leixing,pro字段
就是比如放访客来自北京市时,那么调用pro=北京市的新闻。访客来自天津市时,那么调用pro=北京市的新闻。
如果是国外时,则按时间调用这个数据表的所有字段。
完整的该怎么写。
我0基础。
求助高手一下。


回复讨论(解决方案)

function viewnews( $pro){

select 字段1,字段2,字段3  from B where pro='$pro';
query

return  arry;

}

可能我想的简单点儿,  后来者补充

大点的网站可以用到缓存机制

function viewnews( $pro){

select 字段1,字段2,字段3  from B where pro='$pro';
query

return  arry;

}

可能我想的简单点儿,  后来者补充



我的意思是数据表调用新闻是根据淘宝对访客来源判断的结果。
貌似你这里没结合。

获取到的是国内的地址,就where pro = '$city'
是国外的话,把where去掉就行

select * from A where B like '%北京%'
