　　今天在编辑excel导入时，使用这个的。

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($other));
?>
// js 创建cookie
//
var name = "str1";
var
function SetCookie(name,value)//两个参数，一个是cookie的名子，一个是值
{
var Days = 30; //此 cookie 将被保存 30 天
var exp  = new Date();    //new Date("December 31, 9998");
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function getCookie(name)//取cookies函数      
{
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return (arr[2]); return null;
}
function delCookie(name)//删除cookie
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}
SetCookie ("xiaoqi", "3")
