PHP 读写cookie的语句:
setcookie("user", "Lilu", time()+3600);
echo $_COOKIE["user"];
javascript读写cookie代码:
function SetCookie(name,value)//两个参数,一个是cookie的名子,一个是值
{
var Days = 30; //此 cookie 将被保存 30 天
var exp = new Date(); //new Date("December 31, 9998");
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function getCookie(name)//取cookies函数
{
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return unescape(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 ("lilu", "it's me")
alert(getCookie('lilu'));
页面用不同的浏览器访问cookie就存放在不同的地方,比如IE浏览器的cookie存放在
C:\Users\[your computer name]\AppData\Roaming\Microsoft\Windows\Cookies
在同一浏览器下 javascript产生的cookie和php产生的cookie可以互相访问比如:
alert(getCookie('user'));
echo $_COOKIE["lilu"];
