In what ways can the PHP code structure be improved to avoid potential pitfalls and make it more efficient for displaying forum board data?

To improve the PHP code structure for displaying forum board data, consider using prepared statements to prevent SQL injection attacks, implementing pagination to efficiently display large amounts of data, and utilizing caching mechanisms to reduce database queries and improve performance. 

// Example code snippet for displaying forum board data with pagination

// Establish database connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Set pagination parameters
$limit = 10;
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$offset = ($page - 1) * $limit;

// Prepare and execute SQL query with pagination
$stmt = $conn->prepare("SELECT * FROM forum_posts ORDER BY created_at DESC LIMIT ? OFFSET ?");
$stmt->bind_param("ii", $limit, $offset);
$stmt->execute();
$result = $stmt->get_result();

// Display forum board data
while ($row = $result->fetch_assoc()) {
    echo "<div>{$row['title']}</div>";
    echo "<div>{$row['content']}</div>";
}

// Close statement and connection
$stmt->close();
$conn->close();
