Solution to the garbled code when JS reads the Chinese cookie set in PHP:

In PHP first Use the escape function to encode, and use unescape decoding in js when reaching the client.

The escape function is as follows:

function escape($str)  
{      
       preg_match_all("/[\x80-\xff].|[\x01-\x7f]+/",$str,$r);      
       $ar    =    $r[0];   
        foreach($ar   as   $k=>$v)       
        {            
           if(ord($v[0]) < 128)  
               $ar[$k] = rawurlencode($v);
            else    
               $ar[$k]    =    "%u".bin2hex(iconv("GB2312","UCS-2",$v));   
       }   
       return    join("",$ar);   
}

Example: test.php

<?php
function    escape($str)    {   
   preg_match_all("/[\x80-\xff].|[\x01-\x7f]+/",$str,$r);   
   $ar    =    $r[0];   
   foreach($ar    as    $k=>$v)    {   
    if(ord($v[0])    <    128)   
     $ar[$k]    =    rawurlencode($v);   
    else   
     $ar[$k]    =    "%u".bin2hex(iconv("GB2312","UCS-2",$v));   
   }   
   return    join("",$ar);   
}
$name = escape("深圳人");
setcookie("name", $name);
?>
<scrīpt>
function get_cookie(name)
{
var result = null;
var myCookie = document.cookie + ";";
var searchName = name + "=";
var startOfCookie = myCookie.indexOf(searchName);
var endOfCookie;
if (startOfCookie != -1)
{
   startOfCookie += searchName.length;
   endOfCookie = myCookie.indexOf(";",startOfCookie);
   result = unescape(myCookie.substring(startOfCookie, endOfCookie));
}
return result;
}
</scrīpt>
<scrīpt>
document.write("js:" + unescape(getCookie("name")));
</scrīpt>

There is also another method:

In PHP5 , you can use the setrawcookie() function instead. It is not encoded when setting the cookie value, so there is no need to use the escape function to encode it when setting the cookie. At this time, JS can also read it directly. The value of cookie
