php 通过ip获取所在城市地址信息 获取计算机外网ip
//获取ip地址
//$ip = $_SERVER['REMOTE_ADDR']; //自动获取客户端的IP
//ip对应的地区
if(!empty($_POST['ip'])){
$ip = $_POST['ip'];
//接口地址,这样返回的是一个xml结果集，如图1;
$str = file_get_contents("http://ip.taobao.com/service/getIpInfo.php?ip=".$ip);
var_dump(json_decode($str,true));
}
echo "
";
//获取计算机的外网ip
function getClientIp(){
$socket = socket_create(AF_INET, SOCK_STREAM, 6);
$ret = socket_connect($socket,'ns1.dnspod.net',6666);
$buf = socket_read($socket, 16);
socket_close($socket);
return $buf;
}
echo getClientIp();
$str1 = file_get_contents("http://ip.taobao.com/service/getIpInfo.php?ip=".$ip);
var_dump(json_decode($str1,true));
