What best practices should be followed when incorporating a dynamic calendar feature using PHP?

When incorporating a dynamic calendar feature using PHP, it is important to follow best practices to ensure the functionality is efficient and secure. One key practice is to sanitize user input to prevent SQL injection attacks. Additionally, using prepared statements can help prevent against SQL injection as well as improve performance. Finally, organizing the code in a modular and reusable way can make it easier to maintain and update in the future. 

// Sanitize user input to prevent SQL injection
$year = filter_input(INPUT_GET, 'year', FILTER_SANITIZE_NUMBER_INT);

// Use prepared statements to prevent SQL injection
$stmt = $pdo->prepare("SELECT * FROM events WHERE year = :year");
$stmt->bindParam(':year', $year, PDO::PARAM_INT);
$stmt->execute();

// Organize code in a modular and reusable way
function getEventsByYear($pdo, $year) {
    $stmt = $pdo->prepare("SELECT * FROM events WHERE year = :year");
    $stmt->bindParam(':year', $year, PDO::PARAM_INT);
    $stmt->execute();
    return $stmt->fetchAll(PDO::FETCH_ASSOC);
}
