What are the advantages and disadvantages of using sessions versus tables for tracking forum thread activity in PHP?

When tracking forum thread activity in PHP, using sessions allows for individual user tracking and customization, while using tables in a database provides a more structured and scalable approach. Sessions are easier to implement and can be useful for smaller forums, but may not be as efficient for larger forums with high traffic. Tables offer better data organization and querying capabilities, but require more setup and maintenance. 

// Using sessions for tracking forum thread activity
session_start();

// Set session variables to track user activity
$_SESSION['user_id'] = $user_id;
$_SESSION['thread_id'] = $thread_id;

// Retrieve session variables to display user activity
$user_id = $_SESSION['user_id'];
$thread_id = $_SESSION['thread_id'];
```

```php
// Using tables for tracking forum thread activity
// Connect to database
$connection = mysqli_connect("localhost", "username", "password", "forum_db");

// Insert user activity into a table
$query = "INSERT INTO thread_activity (user_id, thread_id, timestamp) VALUES ('$user_id', '$thread_id', NOW())";
mysqli_query($connection, $query);

// Retrieve user activity from the table
$query = "SELECT * FROM thread_activity WHERE user_id = '$user_id'";
$result = mysqli_query($connection, $query);

// Process and display user activity data
while($row = mysqli_fetch_assoc($result)) {
    echo "User ID: " . $row['user_id'] . " Thread ID: " . $row['thread_id'] . " Timestamp: " . $row['timestamp'] . "<br>";
}
