获取的真实ip，本地测试总是::1 或者127.0.0.1或者局域网的ip ，请上传到你的空间之后访问会出现正常的IP地址

/** * 获取用户真实 IP */function getIP(){    static $realip;    if (isset($_SERVER)){        if (isset($_SERVER["HTTP_X_FORWARDED_FOR"])){            $realip = $_SERVER["HTTP_X_FORWARDED_FOR"];        } else if (isset($_SERVER["HTTP_CLIENT_IP"])) {            $realip = $_SERVER["HTTP_CLIENT_IP"];        } else {            $realip = $_SERVER["REMOTE_ADDR"];        }    } else {        if (getenv("HTTP_X_FORWARDED_FOR")){            $realip = getenv("HTTP_X_FORWARDED_FOR");        } else if (getenv("HTTP_CLIENT_IP")) {            $realip = getenv("HTTP_CLIENT_IP");        } else {            $realip = getenv("REMOTE_ADDR");        }    }    return $realip;}

2.根据ip获取地址

/** * 获取 IP  地理位置 * 淘宝IP接口 * @Return: array */function getCity($ip = ''){    if($ip == ''){        $url = "http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json";        $ip=json_decode(file_get_contents($url),true);        $data = $ip;    }else{        $url="http://ip.taobao.com/service/getIpInfo.php?ip=".$ip;        $ip=json_decode(file_get_contents($url));           if((string)$ip->code=='1'){           return false;        }        $data = (array)$ip->data;    }        return $data;   }

测试

var_dump(getIP());var_dump(getCity());var_dump(getCity('218.93.250.162'));

string(3) "::1"array(10) {  ["ret"]=>  int(1)  ["start"]=>  int(-1)  ["end"]=>  int(-1)  ["country"]=>  string(6) "中国"  ["province"]=>  string(6) "江苏"  ["city"]=>  string(6) "宿迁"  ["district"]=>  string(0) ""  ["isp"]=>  string(0) ""  ["type"]=>  string(0) ""  ["desc"]=>  string(0) ""}array(13) {  ["country"]=>  string(6) "中国"  ["country_id"]=>  string(2) "CN"  ["area"]=>  string(6) "华东"  ["area_id"]=>  string(6) "300000"  ["region"]=>  string(9) "江苏省"  ["region_id"]=>  string(6) "320000"  ["city"]=>  string(9) "宿迁市"  ["city_id"]=>  string(6) "321300"  ["county"]=>  string(0) ""  ["county_id"]=>  string(2) "-1"  ["isp"]=>  string(6) "电信"  ["isp_id"]=>  string(6) "100017"  ["ip"]=>  string(14) "218.93.250.162"}
