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
