总有喜欢瞎猜后台的，发个伪页面代码，可放置在/admin/下
页面如下：
代码：
<?php
session_start();
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
$pageTitle="Login";
$usera="admin";
$passa="admin";
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$username = $_POST['username'];
$password = $_POST['password'];
// 判断用户名和密码是否匹配
if ($username === $usera && $password === $passa) {
// 登录成功，设置会话变量并重定向
//$_SESSION['logged_in'] = true;
//header('Location: admin.php');
echo "<script>alert('不要瞎猜密码，禁止干坏事！');</script>";//恭喜你猜对了，不过没奖励哈
exit();
} else {
// 登录失败，可以显示错误信息
echo "<script>alert('用户名或密码错误，错误5次后封禁ip！');</script>";
}
}
?>
