记录访客的IP所在地

浏览器类型网络类型

以及访问时间和访问地点

还有访问设备

首先涉及几个重要的知识点

1.php取出json的数据

现在有一个json数据
$json = { ["resultcode"]=> string(3) "200" ["reason"]=> string(12) "查询成功" ["result"]=> object(stdClass)#2 (2) { ["area"]=> string(8) "内网IP" ["location"]=> string(8) "内网IP" } ["error_code"]=> int(0) }
//取出result下面的area数据
$city = $arr->result->area;

2.接口的使用

3.日志调试（没有log.txt文件时会自动创建）

在微信开发时常用到的调试办法

    $stream = fopen("log.txt", "a");
    fwrite($stream, "\n" .'所在城市：' . $city);
