What are the potential benefits and drawbacks of integrating a member area with a forum using PHP?

Issue: Integrating a member area with a forum using PHP can provide a seamless user experience by allowing members to access both areas with a single login. However, it may also introduce security risks if not properly implemented.

<?php
// Code snippet for integrating member area with forum using PHP

// Check if user is logged in
if(isset($_SESSION['user_id'])) {
    // Display forum content for logged in users
    echo "Welcome to the forum!";
} else {
    // Redirect to login page if user is not logged in
    header("Location: login.php");
    exit();
}
?>
