【PHP】使用PHP根据用户的IP地址获取地址信息

使用PHP根据用户的IP地址获取地址信息：

'bd_ak' => 'yr0Rm***************24HruOyGE',   //百度地图的ak

function get_client_city(){
    $ip = get_client_ip(); //调用上面的函数进行获取IP地址
    $ak = Config('app.bd_ak');    ///申请的ak
    $url = file_get_contents("http://api.map.baidu.com/location/ip?ip=$ip&ak=$ak");  //调用百度地图开放接口
    $res = json_decode($url,true);
    //数据处理
    $data['login_ip'] = $ip; //ip
    $data['login_xy'] = $res['content']['point']['x'].','.$res['content']['point']['y'];//坐标
    $data['login_province'] = $res['content']['address_detail']['province']; //省
    $data['login_city']     = $res['content']['address_detail']['city']; //市
    $data['login_district'] = $res['content']['address_detail']['district'];//区
    $data['login_street']   = $res['content']['address_detail']['street'];   //街
    $data['login_street_number']   = $res['content']['address_detail']['street_number'];   //街道编号
    $data['login_city_code']       = $res['content']['address_detail']['city_code'];   //城市编号
    $data['login_create_time']       = time();
    //入库
    Db::name('login_log')->insert($data);
}
//表
