怎么使用PHP查询IP地址归属地

// 接口请求Key，可以通过https://www.juhe.cn/docs/api/id/1免费申请开通 $appkey = "*********************";  //根据查询的IP地址，查询该IP所属的区域 $url = "http://apis.juhe.cn/ip/ipNew"; $params = [     "ip" => "112.112.11.11",//需要查询的IP地址或域名     "key" => $appkey,//应用APPKEY(应用详细页查询) ]; $paramstring = http_build_query($params); $content = juheHttpRequest($url, $paramstring, 1); $result = json_decode($content, true); if ($result) {     if ($result['error_code'] == 0) {         echo "国家：{$result['result']['Country']}" . PHP_EOL;         echo "省份：{$result['result']['Province']}" . PHP_EOL;         echo "城市：{$result['result']['City']}" . PHP_EOL;         echo "运营商：{$result['result']['Isp']}" . PHP_EOL;     } else {         echo "{$result['error_code']}:{$result['reason']}" . PHP_EOL;     } } else {     echo "请求失败"; }
