PHP获取ip与ip所在城市
1获取真实ip,本地测试总是::1 或者127.0.0.1 或者局域网的ip
/** * 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'));
结果
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" }
说明:新浪的接口,直接能获取到地址信息,淘宝的接口需要提供ip,不过获取的信息更全面
