Page Load

[NZ_Kiwis]

I want a page which can only be opened by a single user once.

This is my plan

MainPage.php
Must arrive from loader.php
Must check Unique ID - session against Database

If unique session ID does not match what's in the DB then direct to login.php
If arrives direct into MainPage.php redirect into login.php
If no sessions exists redirect to login.php

On a set interval check current session ID against DB - if different redirect to login.php

Loader.php
Sets a unique ID 5446404848de112@5
Set this as a session and into a DB
If a record exist for user the kill older record.

Any comments please

Why only once? i can understand looking to see if it is a returning user, also what prevention's would you take to stop a user simply deleting the cookie/session id to returning to the page you want to display only once?

its a game so single instance only

ideas please

Something like this I guess for a start..

<?php
	require_once 'core/init.php';

if(Session::exists('home')){
	echo '<p>' . Session::flash('home', 'You have been registered and can now log in!') . '</p>';
}
$user = new User();
if($user->isLoggedIn()){
	echo'</a> <br /></p>';
?>
	</div>
<div id ="wrapper">
		<div id="userinfo">
			<a href="profile.php?user=<?php echo escape($user->data()->username);?>"><?php echo escape($user->data()->username);?></a>
		</div>
		<ul>
			<li> <a href="update.php">Update details</a></li>
			<li> <a href="changepassword.php">Change password</a></li>
			<li> <a href="logout.php">Log out</a></li>
			<li><?php  if($user->hasPermission('admin')){
		echo 'Admin';
	} ?>  </li>
		</ul>
		<div id ="login">
			<?php	
			} else {
					require_once 'login.php';
					?>
				<a href="login.php">Login</a>	
				<?php
					}
				?>

	</div>
</div>		

<?php
	require_once 'core/init.php';

if(Session::exists('home')){
	echo '<p>' . Session::flash('home', 'You have been registered and can now log in!') . '</p>';
}
$user = new User();
if($user->isLoggedIn()){
	echo'</a> <br /></p>';
?>
	</div>
<div id ="wrapper">
		<div id="userinfo">
			<a href="profile.php?user=<?php echo escape($user->data()->username);?>"><?php echo escape($user->data()->username);?></a>
		</div>
		<ul>
			<li> <a href="update.php">Update details</a></li>
			<li> <a href="changepassword.php">Change password</a></li>
			<li> <a href="logout.php">Log out</a></li>
			<li><?php  if($user->hasPermission('admin')){
		echo 'Admin';
	} ?>  </li>
		</ul>
		<div id ="login">
			<?php	
			} else {
					require_once 'login.php';
					?>
				<a href="login.php">Login</a>	
				<?php
					}
				?>

	</div>
</div>
