php 来访国内外IP判断代码并实现页面跳转

Jun 13, 2016 pm 12:20 PM
javascript php one time code judgment Domestic and overseas accomplish I plan have Jump page

我大概构思了一下,有两个方案:
1. Javascript判断来访者的浏览器语言,如果是中文系统,自然使用者都是中国人,跳中文网站;

如果是非中文系统,默认使用者非中国人,跳英文网站。

优点:判断反映速度快。
缺点:不准确,有可能中国用户喜欢用英文版系统,或者外国人使用中文系统的情况。


代码

复制代码 代码如下:





2.使用IP库来进行来访IP的判断

优点:判断准确。
缺点:响应速度没Javascript快。

需要引用一个PHP的IP库 ip_php.zip

我在网站头部引用jquery进行判断

复制代码 代码如下:





...


checkip.php页面的代码:

复制代码 代码如下:


$userip=$_SERVER['REMOTE_ADDR'];
//引用ip库的文件 把ip.zip里的全部文件放在lib目录下
include_once('/lib/iplimit.class.php');
$iplimit = new iplimit;
if($iplimit->setup($userip))
{
echo 1;
}
else
{
echo 2;
}



两种方法都可以完美实现判断来访IP,选择哪种就看你的具体需求了。
