How can the code snippet provided be optimized for better performance in handling multiple forum IDs?

The issue with the current code snippet is that it makes multiple database queries for each forum ID, which can be inefficient when handling a large number of IDs. To optimize performance, we can modify the code to use a single database query with the IN clause to fetch all forum data at once. This will reduce the number of database queries and improve overall performance. 

// List of forum IDs
$forum_ids = [1, 2, 3, 4, 5];

// Convert forum IDs array into a comma-separated string
$forum_ids_str = implode(',', $forum_ids);

// Query to fetch forum data for multiple IDs at once
$query = "SELECT * FROM forums WHERE forum_id IN ($forum_ids_str)";
$result = mysqli_query($conn, $query);

// Fetch and display forum data
while ($row = mysqli_fetch_assoc($result)) {
    echo "Forum ID: " . $row['forum_id'] . " - Forum Name: " . $row['forum_name'] . "<br>";
}
