PHP 获取 ip 地址信息之前用过新浪/淘宝的接口，但如果新浪/淘宝接口出问题就没法用了，而且网络获取也慢.
今天介绍一个开源的geoip

淘宝接口

$ip = file_get_contents('http://ip.taobao.com/service/getIpInfo.php?ip=180.149.132.47');
print_r(json_decode($ip, 1));

 [country_id] => CN
 [area] => 华北

 [ip] => 180.149.132.47
 )

纯真 IP 数据库
// 先下文件 QQWry.Dat http://www.cz88.net/fox/  http://update.cz88.net/soft/setup.zip
$IpLocation = new IpLocation('qqwry/QQWry.Dat');
$client = $IpLocation->getlocation('180.149.132.47');
安装 geoip
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/bin/composer
chmod +x composer
composer require geoip2/geoip2:~2.0
使用
require_once 'vendor/autoload.php';
use GeoIp2\Database\Reader;
$reader = new Reader('GeoIP2-City.mmdb');
$record = $reader->city('180.149.132.47');// 百度 ip
dump($record);// dump 来自 laravel
