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>

Copy after login

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(&#39;I am China ip&#39;); 
} 
else { 
//alert(&#39;I am not China ip&#39;); 
location.href="英文网站"; 
} 
}, 
complete:function(XMLHttpRequest,textStatus) { 
}, 
error:function() { 
} 
}); 
} 
</script> 
<body οnlοad="initurl()"> 
... 
</body>

Copy after login

Checkip.php page code ：

$userip=$_SERVER[&#39;REMOTE_ADDR&#39;]; 
//引用ip库的文件 把ip.zip里的全部文件放在lib目录下 
include_once(&#39;/lib/iplimit.class.php&#39;); 
$iplimit = new iplimit; 
if($iplimit->setup($userip)) 
{ 
echo 1; 
} 
else 
{ 
echo 2; 
}

Copy after login

Both methods can perfectly determine the visiting IP. Which one you choose depends on your specific needs.
