Question

我试图从输入帖子发布的数据中处理数组ip。要将此转换为纬度经度，我使用以下代码

这是我的ci库：

<?php defined('BASEPATH') OR exit('No direct script access allowed');
  include APPPATH . 'libraries/GeoIP/src/geoipcity.inc';

    class GeoIp{

        public function info($ip){
            $gi = geoip_open(APPPATH . 'libraries/GeoIp/data/GeoLiteCity.dat', GEOIP_STANDARD);
            $record = geoip_record_by_addr($gi, $ip);
            geoip_close($gi);
            return $record;
        }

        public function get($ip){
            $gi = geoip_open(APPPATH . 'libraries/GeoIp/data/GeoLiteCity.dat', GEOIP_STANDARD);
            $records = array();
            $ips = is_array($ip);
            foreach ($ips as $key=>$value) {
                $records[] = geoip_record_by_addr($gi, $value);
            }

            foreach ($records as $record) {
            $record_string = $record->longitude . "," . $record->latitude;
            geoip_close($gi);
            return $record_string;
            }
        }

    }

这是我的控制器：

public function iplat(){
    $this->load->library('geoip');
    $record = $this->geoip->get($this->input->post('ip'));

    echo json_encode($record);


}

此代码始终返回null

我马上看到的一个问题是你的代码

is_array($ip)

由于您已将$ips分配给$ips，$ip现在是布尔值而不是数组。所以你不能在它上面运行循环。也许你打算像这样运行if(is_array($id)) { foreach ($ip as $key=>$value) { $records[] = geoip_record_by_addr($gi, $value); } }的循环：

        $('#ABC').DataTable({
        "destroy": true,
        language: {
            processing: "<img src='" + $('#ajaxImageUrl').val() + "'/>"
        },
        "processing": true,
        "serverSide": true,
        "columnDefs": [{
            "targets": 0,
            "orderable": false
        }],
        "ajax": {
            url: 'url',
            type: "post",
            beforeSend:function(jqXHR, settings){
                if(settings.nTable.jqXHR)
                    settings.nTable.jqXHR.abort();
            },
            xhr: function() {
                var xhr = $.ajaxSettings.xhr();
                xhr.onreadystatechange = function(){
                    //code
                }
                xhr.upload.onprogress = function(e) {
                    setDesign();
                     xhrCount++;
                };
                return xhr;
            },
        }
    });

我无法将数组中的ip转换为经度和纬度
