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 Chinese and jump to the Chinese website;

If it is not Chinese system, default users are non-Chinese and jump to English websites.

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

Copy code The code is as follows:

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 quoted jquery at the head of the website for judgment

Copy code The code is as follows:

 
 
< ;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) { 
//If the return value is 1, it means the visitor is an IP in China 
if(msg == 1){ 
//alert ('I am China ip'); 
} 
else { 
//alert('I am not China ip'); 
location.href="English website"; 
} 
}, 
complete:function(XMLHttpRequest,textStatus) { 
}, 
error:function() { 
} 
}); 
} 
< /script> 
 
... 
 

Code of checkip.php page:

Copy code The code is as follows:

 
$userip=$_SERVER['REMOTE_ADDR']; 
//Reference the ip library The file puts all the files in ip.zip in the lib directory 
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.
