我一周前刚学php。但现在我有一个问题。我的 php 登录和会话脚本，只在首页工作。当我使用明确的 cookie 进行测试，并在浏览器中输入我网站上的特定页面（例如：www.mysite.com/page34.html）时，登录表单不显示。
为什么尚未登录的用户可以访问我网站的特定页面？
ceklogin.php
<?php
include "koneksi.php";
/* Variable declarationl */
$username = $_POST['username'];
$password = $_POST['password'];
/* check data with my sql db in server */
$user = mysql_query("SELECT * FROM login WHERE username='$username' AND password='$password'");
$match = mysql_num_rows($user);
if ($match==1){
echo "<script>window.location = 'http://www.mysite.com/page1.html'</script>";
}
else {
echo "<h1>Username and Password not match</h1>";
}
?>
索引.php
<?php
if(isset($_COOKIE['AboutVisit']))
echo "<script>window.location = 'http://www.mypage.com/page1.html'</script>"
?>
<?php
$hour = 10800 + time();
//this adds 1 hour to the current time
setcookie(AboutVisit, date("F jS - g:i a"), $hour);
?>

//i am hiding my sql server, username, and password in this post

哪一个是错的？
