如何把二维数组存储到cookie中呢?
先把数组转换成字符串,要用时再去掉斜线(为什么会出现斜线呢?)转换回来
a.php

<?
$cart_info[0][0] = "1123";
$cart_info[1][0] = "5334521";
$cart_info[1][2] = "df";
$cart_info[4][2] = "fefe";

setcookie("xia",serialize($cart_info));
?>



b.php

<?
$other = StripSlashes($_COOKIE['xia']);
print_r(unserialize($other));
?>



// js 创建cookie

//
var name = "str1";
var
function SetCookie(name,value)//两个参数,一个是cookie的名子,一个是值
{
    var Days =30; //此 cookie 将被保存 30 天
    varexp  = newDate();    //newDate("December 31, 9998");
   exp.setTime(exp.getTime() + Days*24*60*60*1000);
   document.cookie = name + "="+ escape (value) + ";expires=" +exp.toGMTString();
}
functiongetCookie(name)//取cookies函数       
{
    var arr =document.cookie.match(new RegExp("(^|)"+name+"=([^;]*)(;|$)"));
    if(arr != null) return (arr[2]); return null;

}
function delCookie(name)//删除cookie
{
    var exp =new Date();
   exp.setTime(exp.getTime() - 1);
    varcval=getCookie(name);
   if(cval!=null) document.cookie= name +"="+cval+";expires="+exp.toGMTString();
}


SetCookie ("xiaoqi", "3")
