//辅助
function getCookieVal (offset) {

//js取PHP保存的Cookie值
function getCookie(sName)
{
var aCookie = document.cookie.split("; ");

var aCrumb = aCookie[i].split("=");
if (encodeURIComponent(sName) == aCrumb[0])

<script>
//显示经过解码的PHP设置的COOKIE
alert(getCookie("phpCookie"));
//使用JavaScript设置COOKIE值
setCookie("jsCookie","我是JavaScript产生的Cookie");
alert(getCookie2("jsCookie"));
</script>
<?php
//显示JavaScript设置的COOKIE的
if (isset($_COOKIE["jsCookie"]))
echo urldecode($_COOKIE["jsCookie"]);

echo $_COOKIE["phpCookie"];
