How can PHP developers ensure accessibility and functionality for users who have disabled cookies in their browsers when implementing a community system?

When users disable cookies in their browsers, PHP developers can ensure accessibility and functionality by using session variables to store user data instead of relying on cookies. This way, essential user information can still be maintained across different pages within the community system without the need for cookies. 

// Start a session
session_start();

// Set session variables
$_SESSION['user_id'] = $user_id;
$_SESSION['username'] = $username;

// Retrieve session variables
$user_id = $_SESSION['user_id'];
$username = $_SESSION['username'];
