如何在不重定向的情况下在PHP中加载页面，基于会话？ [关闭]

Question

I'm trying to create a index.php page that loads either the login page (login.php) or the actual page (main.php) based on the users session.
I know I could do it with redirecting, but I want to simply have everything on one "page".
What's the best way for doing this?

There is plenty of ways to achieve it. Check if the session is current and then display the main.php if so, otherwise display the login page.

if(isset($_SESSION['user'])) {
    include('./main.php');
} else {
    include('./login.php');
}
