我使用会话来登录用户，所以基本上用户存储在会话中。我使用什么代码粘贴到我的以下文件中，以便用户无法访问该页面，除非他/她登录。

    <?php
session_start();

?>

像这样的东西怎么样

if(!isset($_SESSION["user"]))
{
    header("Location: homepage.php");
}

基本上，如果没有用户会话重定向到主页。

exit()or函数，die()或者，如果你想显示某些内容，一个if包含 HTML 的简单语句。例如

<?php if($logged_in) { ?>
<p>You are logged in!</p>
<?php } else { ?>
<p>You're not logged in. Go to the login page.</p>
<?php } ?>
