php Visit domestic and foreign IP judgment codes and implement the page Jump
I recently made a request for the company website: to determine whether the visitor has entered the Chinese website or the English website based on the IP address of the visitor.
I roughly thought about it, and there are two options:
1. Javascript determines the browser language of the visitor. If it is a Chinese system, naturally the users are all Chinese, and they will jump to the Chinese website ;
If it is a non-Chinese system, the default user is non-Chinese and will jump to the English website.
Advantages: Fast judgment and reflection.
Disadvantages: Inaccurate, it is possible that Chinese users prefer to use the English version of the system, or foreigners use the Chinese system.
Code
<script type="text/javascript" language="javascript">
var Browser_Agent=navigator.userAgent;
//浏览器为ie的情况
if(Browser_Agent.indexOf("MSIE")!=-1){
var a=navigator.browserLanguage;
if(a !="zh-cn"){
location.href="英文网站";
}
}
//浏览器非ie的情况
else{
var b=navigator.language;
if(b!="zh-CN"){
location.href="英文网站";
}
}
</script>2. Use the IP library to judge the visiting IP
Advantages: Accurate judgment.
Disadvantages: The response speed is not as fast as Javascript.
Need to reference a PHP IP library ip_php.zip
I reference jquery at the head of the website to make a judgment
<script type="text/javascript" src="/js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" language="javascript">
function initurl() {
$.ajax({
type:"GET",
url:"checkip.php",
dataType:"html",
data:"&time="+new Date(),
cache: false,
async: false,
beforeSend:function(XMLHttpRequest) {
},
success:function(msg) {
//如果返回值为1表示访问者为中国地区的ip
if(msg == 1){
//alert('I am China ip');
}
else {
//alert('I am not China ip');
location.href="英文网站";
}
},
complete:function(XMLHttpRequest,textStatus) {
},
error:function() {
}
});
}
</script>
<body οnlοad="initurl()">
...
</body>Checkip.php page code ：
$userip=$_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;
}Both methods can perfectly determine the visiting IP. Which one you choose depends on your specific needs.
