setcookie ($cookie_name."[2]",'',time()-3600);

Answer 1

setcookie ($cookie_name."[1]",'');
写的不错！确认$action 有值

Answer 2

function logout()
{
print_r($HTTP_COOKIE_VARS);
exit;
//看看有没有你要清空的COOKIE
global $cookie_name;
        // cookie名称用函数定义,函数值为 $cookie_name = "my_amani";
setcookie ($cookie_name."[1]",'');
setcookie ($cookie_name."[2]",''); echo "<META HTTP-EQUIV=REFRESH CONTENT='0;URL=index.php'>";
        // 清空cookie后返回到index.php页
exit;
}
