cookis 设置，读取方法,跨域[二级域名]
$time =30;
$domain ='.111cn.net';
setcookie("abcde","aaaaaa");//最简单的cookie设置方法

setcookie('load','www.111cn.net',time()+3600*24,'/','.111cn.net'); //这里可以设置二级域名
$cookis = $_COOKIE['loadDomain'];//读取域名
print_r( $cookis );
/*

来看几个例子：

简单的：

SetCookie("MyCookie", "Value of MyCookie");

带失效时间的：

SetCookie("WithExpire", "Expire in 1 hour", time()+3600);//3600秒=1小时

什么都有的：

SetCookie("FullCookie", "Full cookie value", time()+3600, "/forum", ".111cn.net", 1);
