今天在工作中遇到一个需要异地登录的功能 如果用户异步登录就提示用户，虽然网上也有很多方法~ 但我这也是一种方法~
$ip = '113.110.179.268'; //ip值 $location = OrgNetNIpLocation::find($ip);//返回式一个数组，索引0 国家 1省份 2城
上面是调用方法，是用TP3.2写的 PHP 版本是 5.6 此类我是放在 Thinkphp/Library/Org/Net 下面
我们调用此方法 然后看看效果
Array ( [0] => 中国 [1] => 黑龙江 [2] => 哈尔滨 [3] => [4] => 230100 )
下面贴实现此方法的代码 【注意我用的是TP3.2】

此方法中需要用到一个文件 因为 不支持该类型 所以 我把他放百度云盘了 密码是 o1r1：~ 传送门：https://pan.baidu.com/s/18Vtxm_QUOiuJh4FTJfJ1Ag
