How can I restrict access to files to logged in users only?

[mesh2005]

I have a folder containing file1,file2,file3. I created a login system that sets the $_SESSION['id'] to a value if the user logged it. How can I restrict the access to my folder? I want the logged in users only to access it. Please help. Thank you

Something like this:

 

<?php

session_start();

if(isset($_SESSION['id']))
{
// Your page
} else
{
// redirect user is $_session['id'] is not set
$page = your_page.php;
header("Location: $page");
}

?>
