PHP获取ip及归属地信息

先获取ip地址

$login_ip = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];$login_ip = ($login_ip) ? $login_ip : $_SERVER["REMOTE_ADDR"];

用获取的IP地址通过网络接口获取ip归属地信息

function get_ip_city($ip){$ch = curl_init();$url = '/ipJson.jsp?ip=' . $ip;//用curl发送接收数据curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);//请求为httpscurl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);$location = curl_exec($ch);curl_close($ch);//转码$location = mb_convert_encoding($location, 'utf-8', 'GB2312');//var_dump($location);//截取{}中的字符串$location = substr($location, strlen('({') + strpos($location, '({'), (strlen($location) - strpos($location, '})')) * (-1));//将截取的字符串$location中的‘，’替换成‘&’ 将字符串中的‘：‘替换成‘=’$location = str_replace('"', "", str_replace(":", "=", str_replace(",", "&", $location)));//php内置函数，将处理成类似于url参数的格式的字符串 转换成数组parse_str($location, $ip_location);// return $ip_location['addr']; # 返回字符串return $ip_location; # 返回数组}

测试

echo "<pre>";var_dump(get_ip_city($login_ip));

结果
