How can PHP developers implement a more scalable and secure user authentication system for individual user pages?

To implement a more scalable and secure user authentication system for individual user pages, PHP developers can use sessions to store user authentication information securely. By checking the user's session on each individual user page, developers can ensure that only authenticated users can access those pages. Additionally, using password hashing and salting techniques can enhance the security of the authentication system. 

<?php
session_start();

// Check if the user is authenticated
if (!isset($_SESSION['authenticated']) || $_SESSION['authenticated'] !== true) {
    // Redirect the user to the login page
    header('Location: login.php');
    exit();
}

// Your individual user page content here
